I don't see how autos could realistically cost $250k each anyway. They are not using significantly more raw resources. Electric cars are an accurate comparison, because they also have top of the line tech in a specific domain - batteries. And volume batteries are a much bigger manufacturing problem than radar systems, which have been assembled (but not at auto-fleet scale) for decades, albeit not with current tech, but much more closer to current assembly than what Teslas LI batteries are. I imagine something like this Google car could go to market for around $80k today, and thats factoring in huge amounts of per-unit overhead for building factories to assemble them en masse in the first place. An auto upgrade kit to a traditional car probably won't cost more than 20k if they permit the retrofitting of old vehicles when the ball starts rolling.
