A driverless car sounds cool to me, think of all the time you could reclaim by having Google be your chauffer! Of course the first issue is getting used to having a driverless car, but I suspect that people will get used to this pretty quickly!
I’m wondering what the insurance carriers will say when you tell them to add Google to your policy. One could argue that rates should drip, if these are as safe as Google claims. And if you ARE in an accident then what better defense is there than “I wasn’t driving, Google was. If you have a problem, sue Google!”
