If this were enacted in the U.S. I would expect the parking spots with charge ports to be filled for hours at a time, using up parking spots for the convenience store. Not the end of the world, but gas station operators and non-electric customers would probably find it annoying. Gas stations are setup to service cars in minutes; to re-charge a similar number of electric cars in the same time would require either new battery technology that can be charged at something like 30C or a huge parking lot. Having more chargers around is a good thing, but gas stations aren't ideal for more than an occasional customer. It might be good in rural areas though that wouldn't otherwise have any chargers, as a sort of emergency backup charging location if some unwary traveler finds themselves without enough charge to get to the nearest city.
