Meh. Typical supercharge for us is 15 to 20 minutes. We have however deliberately used public Chademo chargers with our adapter just to slow things down enough so we could have lunch. That’s probably the only time I have charged for 40 minutes.OK. I don't want to spend 20-40 minutes of my day loitering around any kind of filling station. Maybe that's just me. But I suspect give things a few years to where electric cars are no longer novel and "special" and I will have company.
On road trips a gas stop was never shorter than 15 minutes in our grand Cherokee. We still did the same stuff. Gas, pee, snack. Etc just how we roll.
