I'm sure it's been said many times, but John Cleese did provide a memorable talk on it [1] and particularly touched on the relation to stress. And if anyone feels like they have troubles with stress/anxiety, Robert Sapolsky provides some great insight into how and why it affects health overall [2]. I'm not sure if Sapolsky's material will help reduce stress, but it was pretty entertaining along the way.

Two great speeches that it would be a shame to lose. Now, what was that about keeping up with digital clutter?

What they've already sold may already be out there, true, but more importantly the ccpa gives you the right to opt out of future collection.

Shotgunning the request to the major players may not give 100% coverage, but I think it would at least reduce the amount of identifying information out there which seems like it would be better than status quo.

I'm curious if anyone has tried this at all.

You may be able to pull the fuse for the ACU, but you would be trading the slight chance that you get into an accident requiring restraint and that the inflator has experienced excessive degradation and produces shrapnel, with a much higher chance that you get into an accident that requires restraint and your seatbelt pretensioners and airbags don't function at all since you've disabled them.

These formula student/fsae cars have aero packages which tend to be designed around 30mph average track speeds, so they will get contribution from that, especially in the latter half of the run. Even so, the tire friction involves both physical interlocking due to deformation and chemical adhesion.

You can see the tire warmers in the video being removed in addition to their approach burnout which imparts additional heat into the tires, so that the tires more effectively stick to the ground.

For all of the questions about why they don't compete with dragster techniques, the student race series they participate in has very strict regulations regarding vehicle layout which forces them to be more of an autocross car, these kinds of (heavily couched) records being produced are really somewhat incidental.

OEMs in the US market still absolutely have to meet unbelted crash performance requirements.

Fortunately modern airbags can be a bit more advanced than just having one "tune" for all situations. Depending on whether an occupant is buckled or not, the airbag control unit can elect to provide different amounts of restraint by controlling the timing of dual-staged inflators, and also cushion vents can be opened or closed either passively or electronically based on what cushion stiffness characteristic is needed.

I've heard that people buy seat-belt extenders or plug in a seat-belt behind their back in order to make the seat-belt reminder chime deactivate (and these chimes are only getting more aggressive) but it's worth noting that in any of the vehicles with this kind of conditional deployment logic they're exposing themselves to an even higher likelihood of being injured. Not to mention the people who straight just cut the wires to their seat-belt sensor.

I'm sure many people would love if the unbelted requirements could just go away, but until unbelted occupants stop accounting for such a large share of injuries/fatalities I don't think they will.
