Most gas stations don't have the real estate. It takes 20 minutes just to charge to 50%. Charging needs to happen where people are already going to spend time while their car is busy charging; home, work, commuter parking lot/garage, mall parking lot, etc. Highway rest stops with gas stations and fast food could add chargers in the parking lot and adapt to people eating there instead of only stopping long enough to pee and get take-out/drive thru; it will make long road trips take longer but not acceptably so.
