[quote=@Etcetera] I'm talking about the world being 100% self-driving. I think it'll eliminate traffic because there will be no wrecks, everyone can move at the same speed and stop at the same time, and servers can precalculate routes to take. No variability. [/quote] There'll still be wrecks, and that would require a super AI and would still be really prone to hackers. There are already people who can shut down cars while they're on the freeway, auto cars would just be worse.
