Yes, the NEVI funding requires 4 stalls be installed every ~50 miles on the major highways they identified. (Exceptions can be granted if there isn't a good spot to do that, but they are few and far between. (Like if it is literally in the middle of nowhere, or the utility says that there is not enough power, 600kW, available.)"Requires"?
I have only seen one exception request granted, and have seen a couple exception requests denied.)
