If I may... I think to optimize transportation we have to look at how people drive. We need a type of urban vehicle, a pod let's call it. Seats 1-2. Only needs 70 or so miles of range. For the daily commute. Smaller than a Smart car. That could sell for <$15k and still provide profit since the battery will be very small. Charge at home, charge at work. Jump bikes and scooters are getting popular in the cities. Options now are: Regular car, Bike, Scooter. A pod would fit between car and bike. Then normal car for long distance driving.
