You're assuming the place they stop has an outlet available and they give them permission to use it. Besides, a regular outlet will charge it very slowly. A 30 min food stop charging on 220V/12A is only 2.6kWh. Since the author said it had a 215 mi range I'll assume it had the smallest 75kWh pack. That's only a 3.4% charge (7.3 miles)! In the US it would be about half that since we have 120V outlets.
