We all need to remember that Tesla is breaking new ground - the first with a long range EV - the first with a high speed charging network. And when you're the first, you learn a lot and things change as you get more experience. When launching the supercharger network, they made some assumptions, and they're not modifying their plans based on actual and projected usage. That's OK - and should not be unexpected. So far, Tesla appears to be using the fees not as a source for new revenue, but primarily to help encourage owners to more effectively use the superchargers - which should be a good thing for every Tesla owner.
Tesla should keep the supercharger fees as simple as possible, something like this:
Charging fee: $.25 per minute (commercial chargers have time-based fees, Tesla should do the same)
Idle parking fee: $.40 per minute, starting 5 minutes after charging completes
Annual free credit: owners get a 240 charging minute credit annually on their purchase anniversary
Credit carryover: unused credits are carried over (but cannot be redeemed for cash)
Supercharger problem reports: Tesla app should be updated to allow drivers to send problem reports to Tesla, indicating any issues with the charging spots, such as cars parked that aren't connected to a charger, spots blocked & inaccessible for use, and any technical problems preventing the chargers from working (damaged cables/connectors, ...)
Any system Tesla picks is going to have challenges. Though adding exceptions (like waiving the idle fee if there's an open charger) makes the program unnecessarily complicated, and opens the door for increased support costs for Tesla to track the exceptions and field the inevitable claims when owners believe they should have had their fees waived.
