It’s also a little limited. The supercharger cables are too short to reach many cars and you have to park weirdly and block other stalls. There’s also no OEM trip planner to make use of them to ensure batteries are preconditioned , you distribute load across nearby superchargers, etc.

I test drove the Ariya and I think it had a 4 menu deep manual precondition option. Its OEM charging locator (not planner) was offline and typical legacy manufacturer built-in nav garbage.

Tesla is building new super chargers for a world where every car isn’t a Tesla. Car makers that aren’t Tesla are also standardizing on port placement to exist in a world where Tesla provides the only reliable charging option.

There's an adapter shortage, so that doesn't really work yet.

I don't know anything about that, but that's not really a problem for antitrust.
