@chai2,
Related to people getting hit by a SDC.
I've owned a Prius for about 3 months now, and I really love it, except for one thing.
On an average of once a week at least, adult pedestrians (never children) simply wander into the road in front of my car when it's in electric mode.
Each time it happens, I'm amazed. Isn't this the first thing your mother taught you to do when you were old enough to walk down a sidewalk? Look both ways?
Once the person was close enough that I actually had to slam on the brakes, screeching tires. That stopped him.
I've heard how people think they should put some kind of device making a sound on the car, so the visually impaired can hear a prius coming. Never mind that, so anyone can hear you coming.
I believe if people can so quickly forget to look for cars unless they can hear a motor, they will just as quickly think "Those self driving cars won't hit me. They know to stop."
