I never heard about them. And with the limited information their site provides my initial impression is that this looks incredibly dangerous.

bugsy9246• 7 years ago

Jump on youtube, plenty of timelapses showing its reliability. The predictability of the system partly removes the danger factor and with the driver monitoring system in place, it becomes very difficult to not pay attention. I'd rather have this driving a car on highways than most people I know

StavrosK8• 7 years ago

What is this? The entire site already assumes you know what it does.

sheepdestroyer• 7 years ago

Opensource AI driving kit to mount on your car.

Made by Geohot, jailbreaker of iPhone and PS3 fame

See : https://github.com/commaai/openpilot

onlyrealcuzzo• 7 years ago

So, it appears to be a plug-in system to do automated cruise control and lane assist and driving in stop & go traffic.

Out of curiosity, I checked for my car. It says it's not supported. BUT, Comma is open source, so I could add it myself.

Does this imply they're encouraging anyone to write buggy code and drive their cars with it?!?

StavrosK8• 7 years ago

I found that after I wrote the comment and had the same question. Also, what does "adding it" look like? Do I have to somehow interface it with the car's computer or other systems? I'm rather confused.

big_chungus• 7 years ago

Does this imply they're encouraging anyone to write buggy code and drive their cars with it?!?

The fact that the comma guys aren't locking it down out of a misguided paternalistic belief that they no better is a good thing. Don't blame them for providing the hardware, blame people if they write buggy code. This is analogous to blaming a firearms manufacturer for a murderer's crime.

bugsy9246• 7 years ago

They highly discourage buggy code with no safety checks - I have been one of those people with no safety checks and have since implemented some

paulcnichols• 7 years ago

I agree. Its like they are intentionally being opaque about what the device does.

Izmaki• 7 years ago

The related articles from this website suggest this is a product for automated driving. It's still unclear to me what exactly this product does.

wonderwonder• 7 years ago

Is this still a Geohot project?

qu4ku• 7 years ago

Yes.

agumonkey4• 7 years ago

too bad

chrispauley• 7 years ago

The Comma One source code was put online (I think by the author?) and deemed to be incredibly dangerous. If I recall there was very little error handling. Does anyone know what has really changed since then?

rvz3• 7 years ago

Well, it didn't take me long to find a message about this on the frontpage that clearly says:

Keep your eyes on the road.
"While engaged, openpilot includes camera based driver monitoring that works both day and night to alert the driver when their eyes are not on the road ahead"

Also, if there are deaths around other autonomous systems like we have seen from Tesla and Uber then perhaps they're even more dangerous as they are closed-systems, unlike this then.

bugsy9246• 7 years ago

Yeah plenty has changed since then, there are limits that are checked twice to ensure the driver is always able to take control. If violated, the car or openpilot throws an error openpilot.comma.ai

fabiensanglard3• 7 years ago

Source (i assume you read the source code and know where these checks are)?

agumonkey4• 7 years ago

the tensorflow codebase ? I forgot I read that..

rvz3• 7 years ago

If there is anything about Comma.ai that I have seen beyond the hype of self-driving cars, I see this as substance, unlike the rest of them AI self-driving cars (Except Tesla). The idea to turn your existing car into self-driving rather than spending $$$ on a new one makes sense for those saving money.

Comma.ai is for cars what Linux is for PCs, meaning that you use open-source software and a hardware kit to make your existing car self-driving. Very clever!

macspoofing• 7 years ago

The idea to turn your existing car into self-driving rather than spending $$$ on a new one makes sense for those saving money.

You sure this is where you want to save money on a self-driving system?

God forbid there's an accident, what then? There's no big company you can point at for recourse and I guarantee that Comma.ai isn't going to stand by and accepted responsibility - their website makes it clear that the dev kit does not ship with any self-driving software.

Very clever!

Very dangerous!!

bugsy9246• 7 years ago

It's only a level 2 system and with this hardware, won't ever be level 3

If there's an accident, the driver has to be pretty stupid. it's predictable, you know where its strong and weak points are. It has weak points when the roads get tricky. Previously it would panic through an intersection, this has since been improved upon.

Its eyes don't leave the road, people on their phones do. I wonder which cause more bumper to bumper collisions!

They probably won't accept responsibility, that's on the driver since openpilot is a driver assist system, not a higher level (L3+) self-driving system

numpad04• 7 years ago

Why is it dangerous? Self driving software instances costs a lot to develop but nothing to manufacture, and the cost cannot be used as an indicator of its safety or sophistication, at all.

Fricken4• 7 years ago

Comma and Tesla do driver assist, neither are self-driving.

hurricanetc2• 7 years ago

Someone should tell Tesla because they use that term all over their site, marketing, and tweets.

heavyset_go2• 7 years ago

From Tesla's own promotional video[1]:

The person in the driver’s seat is only there for legal reasons. He is not doing anything. The car is driving itself.

awal2• 7 years ago

When somebody installs Linux on their computer without knowing what they are doing they might make break their computer. When somebody tries to install after-market self-driving equipment in their car without knowing what they are doing they could easily kill people.

ehaisnfn3• 7 years ago

That's really a bullshit comparison. It either works, or it does not. That's quite literally the same as oem systems. It either works, or throws an error and does not.

etaioinshrdlu3• 7 years ago

Comma.ai represents a strange attitude towards life in which you try to turn hard, serious problems (like self-driving), into trivial problems (write some Python and run it on Android phones and plug it into your car!) and try get away with it. It only has a chance of working if you are cool enough in SV such as geohot. I interviewed there once and it was extremely off-putting how clear their demand for fast progress was, and how little they cared about safety.

It's move fast and break things all over again.

Think about how the tech community rips apart Boeing and demands the utmost in quality engineering, reliability, redundancy, testing. And then we have comma, which controls your vehicle on a non-realtime system...

If you ran comma.ai in your car and had a serious crash, you could possibly be found criminally negligent.

kgraves2• 7 years ago

I'm curious about this perspective and would like to know more, could you expand on this?

haecceity• 7 years ago

Apps crash a lot.

gricardo992• 7 years ago

If you'd like to know more specifically about the comma.ai saga, regarding safety and regulation in the U.S., here's some background, previously covered on HN:

https://news.ycombinator.com/item?id=12840368

https://techcrunch.com/2016/10/28/comma-ai-cancels-the-comma...

person_of_color• 7 years ago

Great perspective. Why isn't SDC software held to the same regard as Boeing? The safety framework is the same.

hurricanetc2• 7 years ago

People don’t seem to understand probability and statistics.

chris116• 7 years ago

And comma ai deals with regulation by selling dashcams that can drive a car if the user installs hardware and opensource software.

I use open pilot for highway driving and love it. But Comma AI is intentionally making design decisions to get around regulation.

bugsy9246• 7 years ago

Fricken4• 7 years ago

When did Comma.ai claim they were doing self-driving?

tedunangst• 7 years ago

What are they doing?

Nition• 7 years ago

Well, the website says:

Currently, openpilot performs the functions of Adaptive Cruise Control (ACC) and Automated Lane Centering (ALC) for compatible vehicles. It performs similarly to Tesla Autopilot and GM Super Cruise. openpilot can steer, accelerate, and brake automatically for other vehicles within its lane.

derefr• 7 years ago

If you ran comma.ai in your car and had a serious crash, you could possibly be found criminally negligent.

I don't know that it's much different than using cruise-control and then having a serious crash. If there's criminal negligence when using cruise control, it's because you weren't aware-enough to shut it off when the conditions cruise-control is built for no longer applied; the mere fact of using cruise-control isn't criminally negligent, as long as you're "just waiting for it to slip up so you can take the wheel."

For that matter, the same is true of teaching a teenager to drive. There's no negligence to having them at the wheel if you're ready to supercede their bad driving at all times.

What's suddenly different, if the "thing that doesn't really know how to drive yet, but which you're ready to supercede the bad driving of" is an AI instead of a teenager?

etaioinshrdlu3• 7 years ago

You can get a learners permit to teach your teenager completely legally. You couldn't do the same with a 10 year old...

If a serious crash involving comma.ai went to trial, it would look like the driver was using unapproved, unregulated software, unnecessarily, putting others at risk. Recent Autopilot incidents show us that expecting a human to take over within a second is not reasonable. I would be very worried that the court would indeed find the driver negligent.

bathtub36510• 7 years ago

What if the crash is caused by the device failing? In the case of your car's built in systems, they've been approved by regulators and you probably wouldn't be held liable. If it was an unregulated device that you installed into your own car that caused the crash, I bet the legal circumstances would be different.

mindentropy• 7 years ago

And then we have comma, which controls your vehicle on a non-realtime system...

Lol. This is what I found extremely shocking and is the first thing that I noticed. I don't think anyone serious about embedded design would touch it. They are trying to ignore decades of experience in real time systems and build some hacky stuff and make it open source.

traverseda2• 7 years ago

I don't understand how you'd do hard real-time when one of the major inputs, the neural-networks, aren't deterministic? In a hard real-time system, what happens if your neural-networks are late telling you where the lanes are?

In reality the comma-AI isn't controlling the car, a number of peripherals on the canbus are controlling the car. All those peripherals are hard-real time, and the comma-AI is bridging the non-deterministic neural networks and those hard-real-time peripherals.

At some point you need to deal with the non-deterministic neural networks, and bridge them into a hard real-time control system. People complaining that part of the system isn't real-time just seems like they haven't thought about it very much. Of course the UI and neural networks aren't going to be hard real-time.

skrebbel• 7 years ago

I think their bet is to be acquired by a desperate established car manufacturer, hopefully before someone dies.

tecleandor• 7 years ago

It's move fast and break things all over again.

And this time it's people what they're moving :P

rsync2• 7 years ago

"And then we have comma, which controls your vehicle on a non-realtime system..."

cma• 7 years ago

The safety critical stuff for disengagements and torque limiting etc. runs in real-time in C code on an STM32 micro.

wolkmo• 7 years ago

Compare OpenPilot to other solutions.

Tesla trying to kill someone: https://www.youtube.com/watch?v=0GnysB0rO3s

The super reliable "Level 3" Audi system not being able to go straight on a highway, the most simple problem there is in self-driving: https://www.youtube.com/watch?v=WsiUwq_M8lE&t=297

Several cars "pedestrian safety system" failing on detecting pedestrian (You had one job..) https://www.youtube.com/watch?v=7Y8JG7kepwc

Let's be honest, there is not a single driving assistant that isn't dangerous. Why care for "realtime" if your model tries to kill you once per minute? Realtime is one of the final touches you need to make your software perfect. That's just how the industry works, and if you want to keep up with them you have to go the same route, or do you know of any exception? Most manufacturers tell you that you should closely watch what your car is doing on autopilot, and they limit it's torque and acceleration, so the human driver is reliability, redundancy, testing and the realtime system.

iMuzz• 7 years ago

Quick bit of feedback for any Comma employees lurking:

It took me a very long time to realize that this was a self-driving solution for existing vehicles. The hero just says

"Driven over 6 million miles" and then a "Buy Now".

When I scrolled down and looked at the product and read:

We’ve added an infrared camera to provide 24/7 driver monitoring, an integrated panda, a custom cooling solution, and an OBD-C port with power supplied directly from the car.

I thought it was some kind of dash cam + driver sleep monitor? Also, most of those words don't mean anything to me.

Only after deeply investigating it did I realize that it's basically Tesla Autopilot for existing vehicles.

You have an awesome value prop though, "Bring autopilot features, to your car." Make that clear!

aza05001• 7 years ago

Seriously. The website does a pretty crappy job at explaining what the product actually is.

bugsy9246• 7 years ago

it's a dashcam with a passive driver assist system, the openpilot stuff is a separate product meant to be installed onto the "comma two" by the user

selectodude• 7 years ago

I think that's sort of by design. The NHTSA shut down their ability to sell in the US a few years ago. This seems to be some sort of stealth method to sell it again using the same sort of trick pharmaceutical companies use where they don't have to tell you any warnings if they don't actually tell you what the thing does.

kissgyorgy• 7 years ago

I only knew from your comment what is this after I came back from the site spent minutes trying to find out. For a couple of seconds I only saw the "Buy now" button and I though "Buy what the fuck?" Really annoying design.

stevage2• 7 years ago

Came here to say something similar. I briefly thought it might have been a self-driving add-on because of this bit:

The comma two does not ship preloaded with software capable of controlling your car. Open source software can be installed separately.

But then I figured that if it actually did that, they'd be screaming about it, not talking about how you can watch your drives.

Kind of hilarious.

alpb• 7 years ago

Count me in as well. I came here to make that comment.

I've had to scan the entire website and still cannot find a reference to a simple term like "self-driving" anywhere in the website. It seemed like a dashcam that warns the driver.

JMTQp8lwXL• 7 years ago

If it doesn't say "self driving" anywhere, it might be presumptuous to say that's its intended purpose.

parsimo2010• 7 years ago

While the website doesn't directly state it, the entire purpose of the Comma hardware is to run the OpenPilot self-driving software (or "driver assistance" software, whatever you want to call it). Sure, you can run other software with it, but it works really well with the software that has already been written for it and is available on the same website.

The FAQ clears some of this up (https://comma.ai/faq), but I agree with the idea that it is purposefully obtuse to keep regulators off their back.

tartoran2• 7 years ago

On the 3rd scrolling down "page" OpenPilot , there is a hard to see link "See OpenPilot in action".

When I watched the videos it made it clear what it does, i was lost before that.

z_andrew• 7 years ago

Same! I had no idea what this was even after reading most of the website.

gautamcgoel• 7 years ago

Came here to make this comment! Seems like a cool product - but most visitors to the webpage will never learn what the product does, since it is buried in the page.

DesolationJones6• 7 years ago

It's vagueish on purpose. They only want smart people using. It's still a dev kit. Not consumer product yet.

From comma's discord:

"if people can’t figure out what it is, it isn’t for them"

dyeje• 7 years ago

Yea I had to come to the comments to figure it out.

lettergram• 7 years ago

Came here to say the same thing! Very difficult to understand what this actually is.

pbreit2• 7 years ago

I read the whole website and still not much idea what this is.

eloff3• 7 years ago

I think this is deliberate. It's also why you have to download and install the self driving software separately. AFAIK regulators stepped in and killed comma as a self driving solution, so this is their way of still going forward and trying to maintain plausible deniability. It might not pass muster in a court of law, I don't know, but it should probably keep the regulators off their back.

bathtub36510• 7 years ago

It seems irresponsible for an engineering company to avoid regulators.

tsukurimashou• 7 years ago

I completely agree, I never heard about it before, after looking a few minutes at the websites and some youtube videos I realized it was a self-driving thing you can install on stock vehicles that support it.

Better information / overview.

Look very promising tho!

gambiting• 7 years ago

I literally thought I was looking at some funky games console first....but which you mount on your dashboard for some reason? And even after reading the entire website I didn't get that it was meant to be for autopilot - I only got that after reading your comment.

jrrrr• 7 years ago

This. I clicked from the HN-linked page over to the main page, scrolled through it, and still had no idea what I was looking at.

syntaxing• 7 years ago

Any more info on the hardware used? I'm kinda curious what the new phone and the infrared camera mentioned is.

bransonf2• 7 years ago

Can anyone here comment on actually using a Comma product?

I don’t even drive a car, but I don’t see why anyone would buy something like this yet. My point being that it’s not full self driving, and frankly its safety is entirely questionable.

Self driving is supposed to make driving less stressful, but does having a system like this actually do that? Or does it make you more stressed because you have to be conscious of the computer?

Don’t get me wrong, I like what George Hotz is trying here, but what incentive is there to be an early adopter?

enragedcacti8• 7 years ago

I find driving much less fatiguing when using my Eon (the previous iteration of this product). Taking yourself out of the feedback loop of constantly adjusting steering (and gas if in traffic) makes the experience much more relaxing even though you still have to pay full attention. In my experience, OpenPilot is really rock solid in normal highway driving scenarios and there isn't anything stressful about using it.

As far as safety goes, their safety policy is outlined here: https://github.com/commaai/openpilot/blob/devel/SAFETY.md

the short of it is:

"""

The driver must always be capable to immediately retake manual control of the vehicle, by stepping on either pedal or by pressing the cancel button.

The vehicle must not alter its trajectory too quickly for the driver to safely react. This means that while the system is engaged, the actuators are constrained to operate within reasonable limits.

"""

Those checks are separately coded into both OpenPilot, the self-driving software, and Panda, the microcontroller responsible for communicating between OpenPilot and the vehicle.

NilsIRL• 7 years ago

and the vehicle itself

bransonf2• 7 years ago

Thanks for the perspective.

Do you happen to know what the hardware safety is like? Just curious.

chris116• 7 years ago

I have an eon and love it for highway driving. It makes long trips relaxing. It's basically the combination of really good adaptive cruise control and active lane keep assist. And I feel it's safe within those limitations.

Open Pilot keeps me in my lane on the highway following a safe distance behind other cars. I have a Toyota with TSS 2.0, so the steering is powerful enough on curves. My only complaint about steering is that on tight turns like highway onramps it will slow down a little too much.

While I was driving my last car I got in an accident when I was driving down the highway at highway speeds and everyone in my lane came to a complete stop. I'm convinced I would not have gotten in that accident if I was driving my current car with open pilot active.

djanogo• 7 years ago

Even without openpilot the TSS should have alerted you to brake.

On a recent long trip (24 hour drive) TSS 2.0 by itself made the driving stress free.

It seems like comma is extending the boundaries of TSS by a little bit beyond what Toyota/Honda can legally do at their scale.

whistlerbrk• 7 years ago

This website is so self-obsessed it can't just tell you what the hell the product is.

steakin• 7 years ago

"comma two is designed for permanent installation in your car."

Okay, what's it do?

"We’ve added an infrared camera to provide 24/7 driver monitoring, an integrated panda, a custom cooling solution, and an OBD-C port with power supplied directly from the car."

Great, so it monitors cars... For what? Quick movements? What's a panda? I'd be interested if I knew what it was.

"comes with three free months of comma prime"

So the 1000$ onboard computer that does something comes with a free* subscription.

They need a total marketing rework, can't imagine the sales they've already lost.

agumonkey4• 7 years ago

andrewstuart• 7 years ago

Not a word of explanation on the front page explaining what it is.

fabiensanglard3• 7 years ago

Let's say I order this stuff and flash the firmware of my car.

If there was a bug in comma ai program (like jerking the driving wheel and slam my car in the guard rail without giving me time to react) I guess I am liable?

That sounds like a bad idea.

cyrux004• 7 years ago

they have limits in place so it never "jerks" the wheel. They are liable in the same way that your automatic cruise control would accelarate towards a stopped car

enragedcacti8• 7 years ago

OpenPilot doesn't require you to flash anything to your car, everything is done using the same CAN messages that the stock ADAS system sends. Further, the microcontroller that communicates between OpenPilot and the vehicle is hardcoded to block any CAN messages OpenPilot sends that are deemed to be too fast to react to:

https://github.com/commaai/openpilot/blob/a2ae18d1dbd1e59c38...

fabiensanglard3• 7 years ago

I am not impressed with this source code. Maybe you can tell my why i am wrong.

The safety.h you pointed to is using "int" for variable declaration instead of using stdints to control size. Is there are reason for that?

From safety.h, I tried to follow addr_allowed function parameters. I get here (https://github.com/commaai/openpilot/blob/c025b96e8a15640ee4...) and see this:

int addr = GET_ADDR(to_send); int bus = GET_BUS(to_send);

Where are GET_ADDR and GET_BUS macros declared? There are no header declaration to follow dependencies.

numpad04• 7 years ago

Yes and yes, but the alternative is you never enjoy self driving and the potential it has to reduce fatalities for the rest of your life.

It’s a trolley problem, this thing WILL KILL, the question is how more/less often compared to humans.

PStamatiou• 7 years ago

I clicked around for a while and it took me forever to figure out what this was. For the longest time I thought it was a dash cam. What's an integrated panda? Why do I care about a custom cooling solution?

remir• 7 years ago

Found a video onn YouTube that demonstrate the system a little bit: https://www.youtube.com/watch?time_continue=361&v=GODp6q4Sac...

Pretty cool stuff.

guu• 7 years ago

Since the website is not clear, here is what it is.

Comma Two is an aftermarket dash cam that adds features like adaptive cruise control, automatic lane centering, and forward collision warning to cars using open source software.

It uses a combination of the dash cam and the vehicle’s built in radar to accomplish this. It is able to control the car and receive its radar data by connecting to the vehicle’s OBD port.

The unit is $1000 and also requires the purchase of a vehicle specific harness for $200.

A list of compatible vehicles can be found here: https://comma.ai/vehicles

The source code that performs the driver assist functionality has to be loaded by the user and is available here: https://github.com/commaai/openpilot

There’s also a “prime” subscription which pays for cell service on an included SIM card and allows you to see video footage or location data from your vehicle remotely.

benlc• 7 years ago

There is so many reasons this shouldn't make it to the top of the front page. But here we are...

pd0wm• 7 years ago

https://comma.ai/faq

kgraves2• 7 years ago

The Comma Two looks like a step in the right direction for making existing cars self driving with open source being a bonus with openpilot.

One can say it is like Tesla Autopilot for any car.

Comma’s products explicitly state you still need to pay attention when driving with their system which is almost hard to ignore.

On a more meta note: I find the comments here ironic given this project fits within the spirit of HN and hacker culture but commenters find this project displeasing.

I agree their marketing is kind of vague and needs improvement, but I encourage HN to view videos of the system in action before jumping to conclusions.

mshockwave• 7 years ago

I think Comma is generally pretty good. The only two downsides are:

1. Some car manufacturers will limit the torque applied to the steering wheel. So Comma can only perform small "drifts" rather than full turns

2. The cooling fan is pretty loud

misiti3780• 7 years ago

Serious question: is 80K-130K for a data science position competitive in the San Diego area? Feels a bit low to me but I live in NYC.

https://comma.ai/jobs

heavyset_go2• 7 years ago

It's low.

throwawaymath2• 7 years ago

Considering the people they're explicitly looking for, according to that page:

People who have done well at math competitions (USAMO, IMO, PUTNAM), competition programming (ACM, USACO, codejam, topcoder), science fairs (ISEF, STS), or capture the flag (DEFCON, secuinside, GITS). Those competitions don't just select for ability, they also select for quickness. We are in a very competitive space.

...it's absurdly low. Companies like Google hand out close to $200k total, liquid compensation to new grads who haven't placed in any of those competitions. The people who have ranked in any of those (especially the math ones, and doubly so the Putnam) can easily write their ticket to a job paying double $130k right out of college.

Anyone with that kind of competitive math/programming experience and real world machine learning engineering experience could earn triple that range if they wanted to. That's a ridiculously small and competitive set of candidates to be targeting. It's also not necessary, because strong performance on the e.g. IMO doesn't a priori map to outperformance, on a per dollar basis, writing autonomous driving logic.

Basically: no it's not competitive for San Diego, Comma is asking for wildly overqualified people to sacrifice significant amounts of money to work there, and it's not clear they should be using those kinds of qualifications as a filtering criteria in the first place.

This kind of cargo culting does not inspire confidence in their recruiting.

aetherspawn• 7 years ago

Well, hey, for $1000 I’d almost buy this for the “Tesla experience” but alas it doesn’t support my car (2014 Lexus).

Well done for finding the right price point. You have a solid business case here.

Not commenting on safety like everyone else because it seems from the ISO 26262 (not easy to comply) and architecture that you’ve put some thought into this. Will be good to see it improve further. I understand that you need to sell units to do so, so I do not hold that against you.

bschwindHN• 7 years ago

Who would willingly buy this and install it in their car? Someone who wants to die?

mynegation• 7 years ago

On stage, I asked Hotz about safety issues and concerns, but he expressed confidence that Comma One wasn’t doing anything existing technology on the market doesn’t already offer.

This is a nonsensical reply. Begs the question what is it that Comma does not do that every proper self-driving or driver assistant solution does.

trynewideas• 7 years ago

If the obtuseness is to deter regulators, it's a good thing nobody at any regulatory body reads Hacker News. Right? Because otherwise frontpaging HN would defeat the entire purpose of trying to fly under regulatory radar.

Funny how people are usually piling on Hotz/Comma and lionizing Musk/Tesla... while their software development practices are probably not too dissimilar : https://twitter.com/atomicthumbs/status/1032939617404645376

"Make driving chill"

Yeah, nah. Driving isn't meant to be "chill". Driving "chill" is how collisions occur. Fuck this product and fuck the SV cocksucks making it.

A lot of commaai bashing here.

I was very skeptic too. However using their system for almost an year everyday, I can deffo say it makes me a safer highway driver.

I have overall more awareness of the road since I don’t always have to keep eyes on the lane in front. I look around more around the car and look side mirror/rear mirror more. Once this asshole driver was zipping left and right over taking and was gonna squeeze through us, I could spot him/her from distance and I gave more space. If I didn’t he would have deffo crashed into us. Granted half an hour later he/she did get into a crash.

Another time, car in front suddenly brakes, system immediately alerted and started braking. Even If I was manually driving, I couldn’t have had the same reaction time. Car ahead crashed, ours didn’t.

Some humans are very dangerous highway drivers since they don’t maintain distance with car infront.

This is testament to both commaai and Toyota. I can set I want 2 seconds-ish reaction time with car infront and it always mantains that safe distance. Really neat.

Also commaai driver mobitoring has gotten quite good. Move your eyes off the road for a bit and it yells with an alert to touch the steering wheel and get eyes back on the road. That alone makes you more attentive.

All I can say is give it a shot, it’s quite an ingenous solution to make other brands of cars, highway self lane following.

I’m not gonna say self driving, because essentially it’s a driver monitoring + alert system + lane following system. Very narrow but does a good job at it.

They should move away from using Python in a system like this. There's a non trivial amount of Python code (e.g. [0]) in the repo. The lack of type-safety is just the start of the issues with using it in a project like this.

Geo addressed that at the lex fridman podcast 5 months ago, briefly mentioning type checking as one of the reasons. I think he said they're moving to Go or C

Well, I think Comma gives a tough competition to Tesla given the features which it offers when compared to AutoPilot of Tesla. There are lot of masses who still cannot afford a Tesla( and their $7K package for full self driving cars). Imagine all of (atleast 20 %) Comma AI and Openpilot supported cars actually using this hardware and software in the next 6 months which is way more than the number of Teslas in the market. Also, it avoids the necessity of owning a Tesla. Coming to safety, I believe Openpiot with Comma makes a driver a better and safe driver with driver being attentive. I wouldn't drive a Tesla without being attentive even it offers Level 4 autonomy (because we always need to have an eye on the road and pitch-in when needed as this involves people's lives and there is no single system in the market which is 100% perfect).
