Something I've never understood is why you would want your auto manufacturer to own energy stations. Why wouldn't you just leave that up to the gas stations?
I have incredibly little faith in industries to establish standards nowadays. Every car manufacturer will eventually make their own charging network, all with their own proprietary connectors. Any aftermarket connector to try and work for all of them will be sued out of existence.
You honestly don't want that, but if it's literally the only option (as it is today), it's a huge advantage.
I have yet to see gas stations even attempt to establish the scale of charging infrastructure that Tesla is doing
