> Assume you are traveling down the 405 at 80mph during rush hour. Okay, bad driving choice there. You are 1.5x more likely to die in a collision driving 80mph than if you were driving the speed limit (65mph), since collision energy is proportional to velocity squared. ;) Worst case for ABS failure vs emergency braking failure? Seems like both can easily result in death, and I don’t see reasons yet to believe one is more likely than the other. We probably have a lot more data on the number of deaths lack of ABS has caused over the years than computer braking systems, and the good news is that we can fix computer braking systems right now and forever. The big difference here is control, not outcome. Having brakes seize suddenly is surprising, whereas going from static to dynamic friction when slamming on the brakes isn’t very surprising. Of course we strive to minimize surprise, and of course it’s preferable if cars don’t slam on the brakes without cause.
