You make a totally valid
You make a totally valid point that Tesla currently has a superior, established, and widespread fast charging network that supports all Tesla vehicles. But even though nearly all EV owners will have the need to travel more than 250-300 miles in a single day from time to time, most do not need to make such long journeys regularly or even very often. So even though it is comforting to know that you have superchargers conveniently all across the country/world, most EV owners charge up at home and drive well under 100 miles each day. This was a real issue for earlier EVs with a limited 50-80 mile range, but not so much with the extended 200+ mile ranges of newer EVs (for most people).
