With 5 minute charging, suddenly conventional gas stations can be used for EVs just as they are for ICE. Nice thing about 'plugging in' as opposed to 'filling up' is that a charging car can be left completely unattended (while you go to pay, get a coffee, or whatever).

Seems that the technological barriers have been overcome, now we just need to build out the infrastructure - which could be as simple as retooling existing gas stations. No need to electrify every parking space or such like.
