So... my thought is that in the future AC charging (in cars) will be discontinued and the cars will be DC charging only. Why put the AC charger in the vehicle... put the the AC to DC converter in the wall unit. And as such, lower KW DC chargers will become more prevalent. 10, 15, 20KW will be options. For the small town, perhaps 50KW to 100KW units backed by a power wall to even out the load so it can be driven by a lower KW power feed from grid.
Currently the trend is the opposite. Manufacturers are up-specing to 11kW in car chargers. IIRC even the Bolt now offers a larger charger option.
Tesla can't even shed the 12v legacy system.
