<i>Even if every new car sold is non-human drivable, it will take a couple decades before the entire fleet is wholly autodrive.</i><p>Coincidentally, that&#x27;s about how long a typical urban rail transit project takes these days.  Here in the Seattle area, we&#x27;re looking at a 30+ year timeline for light rail construction.  In military parlance this is known as &quot;fighting the last war.&quot;<p><i>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.
(imho it won&#x27;t ever happen. People like driving cars, but that is a different debate)</i><p>I like to drive, too, and I spend an unreasonable proportion of my own money on cool cars.  But the fact is that self-driving tech will turn driving into a hobby rather than a necessity.  Right now, our &quot;hobby&quot; kills about 30,000 people per year in the US alone.<p>The transition away from human drivers will look like an example of punctuated equilibrium.  It may seem like little progress is being made, but we&#x27;ll all wake up one morning and discover that the status quo has become impossible to justify.  Life (and death) on the roads will change faster than almost anyone can imagine.<p><i>Poor people aren&#x27;t driving new teslas.</i><p>Not a problem, because the idea that everybody has to own one or two cars to be a full-fledged adult is going to become obsolete at around the same time.
