Jaywalking is a crime for a reason, because it's potentially deadly to the pedestrian. It seems to be much worse in small/mid-size cities (probably because of less overall traffic). I've had people literally jog into my lane then walk the remaining 4 feet to the sidewalk while I slow from 35 to 10 to avoid hitting them. I think if half the cars on the road are autonomous and will just stop no matter what you will not see the decrease in pedestrian injuries and deaths some are expecting.
