that's a great suggestion above, that this be payable via the Tesla app. maybe even simpler to pay / make a reservation all via the touchscreen.
actually, the touchscreen could work together with the GPS and the reservation system to advise drivers of any delays at the swap station. wishful thinking considering the speed of Tesla updates (the swap station going live comes 18 months after their first announcement), but it's still great news to see this actually starting to happen.
