and those who are truly unaware things like buried wire roadways for vehicle control have been speculated about since I was a teenager reading Mechanics Illustrated. Such an approach might be feasible but please don't ask me to share my road with them. That is just pushing the technology on the cheap instead of building dedicated roboroads. It also still doesn't address mechanical failures by roboroad users, something that is a recipe for disaster in a system when such a failure causes a pileup.

I hate to say never but there is no technology that can think as quickly, weigh a large number of options, make decisions and execute them as quickly as the human brain. The number of observations, decisions and executions one makes just backing out of the driveway is enormous and largely unappreciated. I cannot imagine sharing a high speed highway with a mix of human and computer drivers.

Not saying of course that competency among us humans is a given.
