Yes, yes, I'm sure you can imagine any number of situations where your lightning reflexes, superb judgement, and superhuman driving skill will produce a better outcome than some dumb automated system.
But even if you are much more skilled than the average driver -- and it does seem like 80-90% of drivers are quite convinced that they're "better than average" -- you're still likely to do dumb things behind the wheel more frequently than you do brilliant things behind the wheel. If you have a human brain, you're kind of stuck with that. There are a million things that can distract you, impair you, or confuse you, and any one of them will knock you down from that pinnacle of performance.
There will certainly be times when an automated system produces a worse outcome than a skilled human driver. But those times will be overwhelmingly outnumbered by the times when it's the other way around. It's really, really hard to reason objectively about risks like this, especially when there's a perceived loss of control involved. But if you don't let objective reasoning drive policy, you're going to end up with more dead and injured people.
When I was a kid, the debate was over seat-belt laws. There were an amazing number of people who absolutely refused to wear them. "I remember this person who was trapped in a burning (or sinking) car because they couldn't get out of the seat belt!" "I'm too good a driver to get into an accident where I'd need a seat belt to save me!" "If I'm wearing a seat belt, I can't be thrown to safety, so I'll be trapped in the collision!" Yes, I'm quite sure that some people have died because of seat belts. But that number is absolutely dwarfed by the number of people saved by them. It's cold consolation to the handful of seat-belt victims, I know, but you're still an utter fool if you let those few tragedies convince you not to use the belt.
Please don't let fear of a few extremely unlikely scenarios block a robust solution for an entire class of common problems.
