Re: Sensors and transponders better than cameras?
I'm rather dubious about cars being able to discern the wide variety of road conditions anytime soon. Puddles? Boards or tire shards lying in the road? Golf ball or softball-sized rocks? (God forbid your car ignores larger ones than that) Broken glass? Ice or slick spots where water has come across the road? Ruts or potholes?
There are lots of things out there that I'd be pretty concerned about my car deciding that it could charge through at the posted speed limit.
Maybe in 10 years, but I don't see it for awhile. Plus there is the "hacking and tracking" risks.
