Some US chains are primed for this, or at least pretty close. Wawa, Buc-ee's, and similar, have ready made and made to order food, restrooms, and many have shopping as well. They aren't full sitdown restaurants, but they could optionally add seating areas if they didn't want to just let people eat in their cars.

So pretty much they just need to find space for the car chargers at their normal parking spots, and maybe add some more spots to deal with increased demand in the future. I've seen both Wawa and Buc-ee's testing chargers at some of the locations, so they're definitely moving in the direction already.
