Disagree, dealership locations are often not well located to be charging stations and there are long stretches of interstate highways where there are no dealerships at all.The big players still have lots of franchised locations on major freeways throughout the country. If they accept EV is in their own best interest, a strong network of chargers would be feasible.
Furthermore, dealerships don't want to sell EVs. They are just as short-sighted as the manufacturers. They will resist charging stations and the manufacturers cannot force them to accept them.
