This is definitely along the lines of what transportation tech has done to date. Instead of new replacing old altogether, the options just get more flexible over time, easier to &quot;packet switch&quot;. You don&#x27;t take just the bike or the bus, you take the bike to the bus and open up a set of possibilities different from the two alone.<p>Likewise with the new generation of small EVs, visual processing, and networking, you can scale the infrastructure for everything more exactly, with a variety of vehicles of different sizes and carefully synchronized transfers, instead of forcing car traffic into primacy.<p>From that perspective it&#x27;s easy to see why PRT was a hard sell - it&#x27;s less flexible than a car and it doesn&#x27;t have the capacities of light rail. The automation part has stuck, though.
