That's true. But by the time EVs make up a significant portion of the vehicle fleet in those areas (enough to justify a rescue van with onboard charging!), chargers will be much more common. Also, by nature, most "ran out of charge" incidents will happen near a charger (or near home, etc) because the driver thought they could make it. It's not likely that someone would drive off into some really remote area with no idea of where they would charge the car.
