is it really gone? Tesla will still have a OEM advantage here in the software and internals. Alot of the "Technology" here is the software that does thermal management and the like. Tesla's still charge faster on a supercharger than a ford f-150 would, and i imagine some future where buying a Tesla gets you "Credits" to use at the chargers.
Tesla has much different goals than the other car manufacturers. Although energy sales are only around 5% of total revenue, Tesla expects that to change going forward.
