If your driving in one day is over 200 miles, and you use Superchargers, you will not be charged a fee.
If you use Superchargers as a convenience in regular daily driving < 200 miles (24-hr period), you will be charged some convenience fee.
Tesla/Musk I hope have thought of this solution. TOTALLY fixes the concern re: Superchargers being unfairly used at the expense of the entire ecosystem.
