Or, like with other automated equipment, people learn to not do stupid behavior that will get them run over. For example, we all just know not to step in front of a train. We have NO EXPECTATION it can stop. Do accidents happen? Yes, but only at the fault of the pedestrian (intentional or not). If we all know that every car won't stop for us in between crosswalks, we may still jaywalk but we'll be danmed sure a self-driving car isn't coming. Right now a lot of people jaywalk and are overconfident if a car is coming it'll stop.
