Car culture in the US is toxic, and a lot of accidents and fatalities are a result of how poorly designed our infrastructure is. We design for cars, not for people (just one more lane bro, will totally fix traffic. Nevermind that a train can move double the capacity of that entire line of traffic).

Cars are the wrong solution, particularly in urban areas. A self driving car is still a car, and comes along with all the same problems that cars cause.
