So much wrong with this logic: "If autonomous cars are even just 1 percent safer than humans, we should still be using them." Does that "humans" include drunks, idiots, and teenagers? If so, I'm sorry, I would never use that car. I'd like to think I drive 2x safer than the average idiot out there.
I took that statement to refer to the cumulative effect of autonomous cars -- Those people you describe are already on the road with you, whatever car you're in.
