New Transport Tech May Repeat Car's Decentralizing Pattern
Source: Marginal REVOLUTION
The question of whether autonomous vehicles, e-bikes, and hyperloop concepts will concentrate or disperse urban populations hinges on a historically overlooked mechanism: technology doesn't determine density outcomes, pricing and policy do. The automobile didn't inherently sprawl cities—zoning laws, cheap gas, and mortgage subsidies made sprawl profitable, while transit-oriented cities like Manhattan and Tokyo remained dense despite car ownership. Autonomous vehicles will sprawl cities if surge pricing or congestion fees apply to dense cores while suburban commuting is subsidized. They will concentrate population if cities aggressively restrict parking and tax distance-based travel. The decisive factor is political: which cities will actively price and regulate new transportation rather than letting market forces and incumbent real estate interests reshape them.
