I think eventually, car ownership will go down significantly, since companies managing fleets of electric cars can do it far more efficiently than private ownership of long range cars. Uber is faster than walking to the car you parked half a mile away. There's always 'free parking' for your large house party in the city. You can also create small cargo only cars for small deliveries like that laptop situation. It's far more efficient from an energy/vehicle cost/liability stand point. Amazon prime 'local' might just replace stores from a pure efficiency standpoint. The number of total cars neccesary will decrease and the large amount of real estate devoted to cars will decrease significantly. Car maintenance costs will decrease with predictable schedules, and economies of scale that come with fleets.
