IMHO the state of the charging network is a major disincentive against buying any CCS equipped EV in the US. Fortunately over the next couple of years every company is switching to NACS and will in theory be able to use Tesla's charging network. This is not great news for the cars bought this year or next though, it would be like buying Betamax.
NACS is CCS with Tesla's plug on the end. 2019 Teslas and earlier won't be able to use it without a CCS retrofit.
You'll be able to use CCS cars can use a passive adapter. And maybe some manufacturers will also offer retrofits.
The EV infrastructure situation in North America is stupid and will take a few years yet to shake out. The failure to standardize has been a stupid waste of time and money for everyone.
If all the adoption does is mean you can use Tesla chargers, that's not a great positive. If existing stations upgrade the plug it doesn't make the charging station any more reliable or the payment system any better.
Right, what will happen is, everyone will start charging at Tesla chargers, and the other companies will consolidate until they can convince people they are reliable enough to try.
