Why does it have to involve the govt or automakers? Last I checked Ford doesn't own any gas stations. Once we hitting a tipping point in EV adoption, private companies will come in (initially with govt subsidies which is what I hope from the infrastructure bill) and build the networks. I fully expect gas stations themselves to start adding charging stations in coming years. They may even subsidize the cost of electricity as people will be hanging out in their stores for 15 mins buying much higher margin items than energy (margins on gas sales are famously low - they want you buying food and drinks inside). I think charging stations will soon just be simple credit card operated like gas pumps so you won't care what network you are using. You will just look at location and price, like people do with gas today.You are being overoptimistic (IMHO from my 30 years of EV experience), especially the infrastructure bill part.
Neither the government nor the legacy automakers have the will, foresight, attitude, or intelligence to create a good charging network. They are too focused on the past to be able to see the future.
