Re: Chaotic California roads ?
"I also wonder how these cars are at passing. Getting behind some tourist who is scared *hitless and driving in the middle of the road at 30mph can get pretty tedious after 10 miles, and I do think that it takes a real person to figure out how to deal with that in a safe manner."
The safest thing to do in that situation is to sit behind them until they pull over or turn off somewhere. Passing them, especially if they are driving down the middle of the road, is certainly NOT the safest way to deal with the situation. Computers don't acknowledge tedium or frustration, so in this case the self-driving car would get its occupant(s) to their destination with much less risk than a meatbag driver would, albeit a fair bit slower.
