The real disconnect is fitting this into the California six lane wide, one person per car, ego show.
Have it be a limousine service. Have Bentley or Maybach build the carriers. A 60 inch LED display should be able to fit in one end. Google’s strength would be predictive analysis of where the units had to be situated. The units would drive themselves to their next pickup. Sell partial ownership. Uber your car out at night to make money. Have a self cleaning unit drive drunk people home.
