I'm pretty sure it's already been invented as all good inventions are, but I think the commentary is the selling point - fuck bad drivers indeed. ED sounds just as annoying as the voice on Google Maps though, if not more so.
The capacity for robot error is a bit worrying: "I'm not tired, ED, I'm just squinting!".
still, it's a much needed solution to a big problem. On teh weekend some speeding idiot went through two fences and ended up upside down in someone's yard. We heard it from our place. He walked away without a scratch! Bizarre. Could have been worse though. You could call it Darwin Awards but the fact is bad drivers kill other people too!
