I admit I post about self-driving cars in part to troll my own blog. For some reason it's a subject that pisses people off (Just a few, but I find it funny that it pisses people off. Who cares if I'm wrong? Get mad when I advocate banning them, I guess).
I actually do think they'll probably be a Bad Thing (not for all people or applications of course) if they do work, but I don't spend much time worrying about that because I don't think they'll work. They are already being used as an excuse to halt investment in other transit modes, and starting to be used an excuse to get public money. That annoys me. But otherwise, it's just talk for me. Gotta talk about something.
