When I saw the announcement of the Rivian pickup, I was so excited I could barely contain myself but, as a Tesla owner I can’t imagine not being on the Tesla network. It’s totally worry free and highly reliable. The standard should be the Tesla network. Using disparate systems adds to the confusion and hinders EV adoption.
Of course, in such a system, the non-Tesla companies would be required to add to the network. The number a stations and chargers they would be required to add would be dictated by their sales numbers. A consortium of those EV companies, led by Tesla, would need to be formed to determine where new stations should be added. This would result in a network that would be recognized across the nation and lessen the confusion, especially by current non-EV owners.
The Tesla network is the best logical choice. With the market penetration and brand recognition Tesla has, having other car companies join the network would be yet another nail in the coffin of this ICE world we still live in.
