40k+ people die per year in car accidents in the US alone. I would say "move fast and break less things" is better.
1. Actual car checks everywhere. I've seen some crazy cars in the US that would be impounded ASAP in most of Europe.
2. Add pedestrian safety requirements for new cars, which would practically ban tall cars (trucks and SUVs) except for professional use.
3. Something for smartphones, not really sure about the best attack angle.
This "might not ever happen" self driving shtick is just moving the goalpost into the middle of nowhere.
Please be careful not to conflate the goals of capitalism with the goals of technology and science.
