Hmmm something about a tiny automotive vehicle with a top speed of 62 mph and maybe a 80ft braking distance makes me feel more comfortable with getting into one.

Certainly a higher error tolerance and lower risk of fatality as compared to a 5000 lb Tesla that goes to 0-60 in 2.4 seconds and takes a football field and a half to slow down.

Maybe they should just make all self-driving cars weigh 1500 lbs and top out at 45 mph. Not a big deal when they run into each other, like bumper cars.
