We used to tell jokes about what cars would be like if they worked as badly as computers. That's starting to be the reality now. I've heard stories of entire cars refusing to run because the computer that controlled the headlight washer fluid broke down. One company recently decided to install DRM on their batteries on a permanent rental scheme. Pretty soon, yes, you might have to stop on the highway to reboot your car to get it working again, and it's not a joke. Welcome to the future, where nothing works quite properly, but it's all supposed to be awesome.

PS - That's kind of the bleak side of robot cars, I guess.
PPS - Google tends to do good work, though, so theirs might not suck.
