But they still pretend that you are saving time by not stopping for gas, and ignoring the 6-13 hours it takes to recharge for the 99% of customers for whom all their stops are not at a SuperCharger stop, and also ignoring the time spent driving out of one's way to find a charging station.
Accounting for that time, let's call it 100 hours a month since this whole page at Tesla is about making up numbers, at the new $50/hr, adds $5000 a month to the cost.
As long as Tesla is going to account for time one spends or loses as a result of refueling, the proper way to do this is to take all the time into account. Cherry picking one aspect of it is not honest.
