Gas stations make much of their money from the convenience store. The margins on the gas itself are pretty thin. The fact that electric cars take longer to charge means it's more likely that people will venture out of the car to browse the store.
I understand that, but I think electric cars will make total number of trips to petrol station much smaller. It doesn't matter what percentage of your profit comes from the store part of the business if your customers no longer visit.
I don't own an electric car, but I would think that if I were charging at home every night (or at more and more carparks), a trip to the petrol station would almost never happen.
