Self-driving is also a long way off in terms of the entire fleet.  Poor people aren&#x27;t driving new teslas.  Even if every new car sold is non-human drivable, it will take a couple decades before the entire fleet is wholly autodrive.  It would also be naïve to assume that any future tech will dominate the market when there isn&#x27;t even a product yet in the market.  City planners cannot take autodrive for granted.<p>(imho it won&#x27;t ever happen.  People like driving cars, but that is a different debate)
