I don't think it's entirely fair to expect Tesla to _wait_ for the rest of the car industry to agree on a standard that suits everyone. When the Model S was developed, no other car company except Nissan had any notable interest in electric cars, and no other company had plans to make cars even _close_ to Tesla's in terms of battery capacity.

Assuming that a charger network was necessary for success, which I would argue it was, waiting for the others to catch up could have killed the company.

Note that there have still been no large-scale deployments of charging standards with more than 50-60kW of power, which is half what Tesla is currently deploying to most of its charging stations in North America.
