It's obvious to me that no other car manufacturer is going to include Tesla Supercharger compatibility. https://arstechnica com/cars/2016/11/bmw-vw-ford-daimler-team-up-for-electric-vehicle-charging-network-in-europe/ https://cleantechnica com/2017/03/27/volkswagens-2-billion-settlement-diesel-emissions-cheating-will-see-400-ev-fast-charging-stations-built-usa/
which is a darned shame.
Tesla knows more than I do about the near future of fast EV charging. Assuming they agree with me, will the Model 3 come with a CCS port and a Tesla adapter, rather than a Tesla port and J1772 adapter as is currently shipped?
Tesla could certainly push forward with the Tesla proprietary network, but 5 years from now they'll end up supporting a network for their vehicles, when every other EV manufacturer will be simply putting a CCS receptacle on their cars and letting EVGo and ChargePoint handle the distributed charger problem. That's an extra cost for Tesla that Ford, GM, VW, BMW etc., wouldn't have to pay.
