We use a mono repo and feature flag new features which gives us the deployment control timing.

Reminds me of the cable internet I had in college. Every night it would drop for several minutes at a time. My homework included cisco labs using equipment we had to reserve remotely so loosing my SSH connections was maddening.

Numerous phone calls and technician visits. At some point was logging into the cable modem to measure the signal strength. Eventually a tech moved my coax connection at the drop? Problem went away, they said another tech would come back out and check on it.

One week later outages again. Lucky for me they offered one month money back guarantee. I returned that modem on the very last day to the dismay of the receptionist.

Reminds me of a Django project rewrite I got to work on very early in my career. I was able to convince the lead to stave off JavaScript because I could barely read Python at the time. I did however fail to convince my colleagues to write unit tests.

Even at steady state cruising the the tires are flexing and stretching with each revolution. Tires are round but a driveway is flat. If you look at the contact patch of the tire it flattens a bit to confirm to the driveway's shape. Now visualize with each revolution that flatten part of the tire is cycling around the wheel.

At a microscopic level there's a lot edges in the road surface that we don't fully appreciate which also contributes to tire wear. http://insideracingtechnology.com/tirebkexerpt1.htm
