I agree that GM is dropping the ball on leveraging the dealer network for DCFC charging. There is no requirement that the chargers be publically available or accessible 24/7. Dealers should see chargers as a potential income source, as they sure won't be doing a lot of oil changes on EVs.
Also, the DCFC charger I used recently at a PA dealership was only 24kw, which is pretty weak for fast charging, it's actually half-fast charging. Not sure if GM has any requirements for newly installed DCFC at Bolt dealerships, but I sure hope the new standard is better than 24 kw.
Chevy has over 4000 dealerships in the USA, that would be a great network, and a great selling point for any GM EV if owners could get free or reduced cost charging on that network, and if the chargers were actually fast chargers of at least 48kw capacity or higher, the Bolt can use chargers rated at up to 80 kw.
