Take NYC for example. MTA enables transportation to just about anywhere in the city, all through an electric, mass-transit trolley system.
If we look at the history of municipal transportation, it looks pretty clear that trolleys were winning over the majority of the car industry up until GM took over trolleys[1] and shut them down to essentially require people to own cars to do any transportation outside of biking and walking.
I think what Tesla is doing is wonderful, but I feel like the problem they are having to solve didn't need to exist in the first place, and the petrol car industry got us in a bad situation.
