The one thing mankind is good at, is mobility. From walking to running, horses to horsepower, swimming to rowing and sailing, Earth to the moon and beyond. For that reason, elimination of private ownership is hard to imagine (at least in the West). It's unfortunate (at least in the U.S.) that in the rush to individualism after WWII, we dismantled urban public transportation systems, trolleys and trains, etc.that should be part of an environmental solution.
My guess is, at some point, 'daily driver' needs can be adaquately met with public/shared options. Let's face it, few people use the cars parked in their driveways 100% of the time so fractional or shared use has merit. And would we then need as much black asphalt? I do hope there will always be a place in our garages for toys. Maybe those toys get taxed differently.
