This is a very common misconception. These vehicles will not have access to the full network. They’ll have access to about a 1/3rd of it.
Telsa’s North American network is over 50k chargers, but these companies are all advertising that they’re going to have access to just over 15k chargers.
Moreover, if you look at Telsa’s network map, they have already defined which charges are all EV, non-Tesla NACS, and Telsa Only. And Telsa only is exactly what it means. No Fords or GMs.
