At first I thought the comparing the gasoline stop against the Supercharger would give the gas stop the edge every time. It really doesn't.
And it's important to note that this is all on the 'old' Supercharger at a max of 120 kW. The upgrade to a max of 145 kW is happening currently (side note, the delta being added is close to the average 'fast charge' rate for my old 2017 Nissan Leaf--the delta!), and over time we'll have charging that peaks at 250 kW. This means that before too long the average Supercharging stop time will drop by around five minutes, and in the medium term more like ten minutes. At that point, even those who want to get back on the road as quickly as possible won't have much to complain about.
