My car (2017 Honda Accord) has a 500+ mile range on a tank of gas. It'd take over an hour to charge to 500 miles.
Even at 15 minutes that's a lie. It takes no more than 2-3 minutes of actual pumping to fill my 500+ mile tank of gas.
Also in NJ it definitely doesn't take more than 5 extra minutes waiting for the attendant 95% of the time.
that said, even at a full tank, that's only 220 miles for me, so unless I'm leaving Oregon on a trip, a 15 minute charge sounds amazing.
the good news is that I've not seen a charging station that had an attendant.
