Dan Neil:

The absurdity of our century-old, ad hoc approach to mobility is captured in one statistic: The utilization rate of automobiles in the U.S. is about 5%. For the remaining 95% of the time (23 hours), our cars just sit there, a slow, awful cash burn, like condos at the beach.
 
 But what if, like condos, automobiles could be shared? It’s one of life’s first lessons—how to share toys, parents, rooms, feelings. But as little consumers grow into adults, they forget the joys of selflessness. That’s about to change. And I don’t mean the collaborative consumerism we see around us—peer-to-peer transportation like Uber—which is symbolic and transitional, lasting only until automation happens, at which point we can get rid of the wetware. And by wetware, I mean us.
