We know that, but also we ought to know that pushing through the hard problems by rolling out systems operating world-wide and interacting with real people is the only way forward toward improved safety, reduced mental slavery to the menial task of driving, and the time and relationship freedom that comes with it. So yep, I let my Tesla do lots of driving. And I do it knowing that the brake pedal and the steering wheel are both manual controls that I can use to override the car at any time, no matter what. That is why I feel so comfortable.

And you know what? It's wonderful. It really is. I am free to look around and see other people on the freeway. They look so bored. So tired. So used up. Meanwhile my wife and I, we turn on the careoke machine and sing our way to the destination. It is absolutely the way to go. You can take my Tesla and its AP functions out of my cold dead hands. Maybe that's how I go, and I'm alright with it.

I wouldn't feel comfortable in a vehicle that may, or may not react to some situation on the road ahead. Because one day it will decide to do $something_really_stupid and you won't be able to react in time/correctly because you'll be too busy singing karaoke. With some extra bad luck, you'll die/kill someone else because of that.

Yeah, but is that a bigger risk than some dumbass in a truck blowing a red light and plowing into my door? Based on where Tesla is at I don't think it is. They're already reasonably below the median risk we all accept for driving at all. After all, my butt can feel that the car is doing something seriously unexpected way before my eyeballs can. So I'm going to keep singing, with my thumb gently on the wheel and one eye on the road.

With all due respect, that is just as likely to happen with human drivers as well.
