That may have been the case before, but I'm not buying that today. I think Tesla needs urban chargers to make money to cover the loses of the rural chargers. Plus that's where the majority of the electric cars are registered.
Not everybody can install a L2 at home. And when people travel, they oftentimes travel to cities, and need to charge there. The busiest I have ever seen Electrify America was at a station just out of Philly. Of the 8 stalls, 5 were in use (2 ID.4, 1 Mach-e, one etron, and one Bolt).
Around Huntsville AL, an L2 EVSE gives 28-32 miles an hour, 208 - 240 VAC. The Space and Rocket Center is the only one with a fee. Most of the Tennessee L2 EVSEs have a fee but it varies. So the ~17 mi to the closest SuperCharger, a V2, 150 kW unit is not a hardship. Bob Wilson
