If I had any money, I'd probably take you up on that. I think the technology might be ready in that time frame, but bureaucracy and safety concerns will push it back. We don't know how well the vision/detection methods of driver-less cars will handle certain scenarios, like a solar flare, or direct subversion from other humans. Would someone be able to disable my car from moving and rob me with a few small devices?
I agree that bureaucracy is the main hurdle. The technology is so close but I'm not sure that the populace or the government is ready.
But malicious agents can disable your car today. A solar flare would fry you current car's electronics just as easily as an auto-auto. And a gun qualifies as a "small device" too, so I'm not sure why that makes in difference.
