The problem is there are no
The problem is there are no 350kw ccs chargers in the world. The tesla is at least far ahead of ccs because there's a world wide network of high power chargers, and also teslas have adapters for all the major power standards (even chademo). How long until there is even 5 high power ccs chargers in the north america? I don't think there's a single one today, although porsche is working on a plan for their cars.
Tesla does need competition to push them along. That would be comparative cars priced about the same or less, and rival charging networks to push them to up their game.
