Honestly I'd trust a computer driving a car a million times more than most of the morons driving out there. Yes I rode a motorcycle nearly every day for over 10 years and barely a day went by when some numpty didn't try to kill me.
And seriously, if I was stupid enough to step in front of a car, I'd trust the computer's reflexes way more than a human's.
I actually did some work on driverless cars and related technologies many years ago. I came across an interesting paper that looked at adaptive cruise control and the effects it has on traffic flow. It was computer modeled, but basically something like 10% adaptive cruise control vehicles was enough to dramatically improve traffic flow. You can think of them kind of herding the rest of the idiots out of the normal speed/stop/speed/stop routine that so messes with smooth and efficient traffic flow. It was very interesting.
TLDR: even a small number of computer controlled vehicles on the road can have significant benefits for all road users.
