I think this is a literal example of a solution searching for a problem. I charge my car at home. Not everyone gets to do that, but solving that issue is a better use of resources. On a road trip the 20 minutes of fast charging is welcomed. I would stop even if I was charging while driving.

Having 16A of charging hanging off light poles and meters on a street in front of an apartment is a better use of resources than wiring the road. Having adequate DC charging is a better use of resources than moving the goal post to “which length of road can I charge on?”
