What do they define as "long distance driving?" I have a 25-mile commute (each way) during the week, about half of it highway. I hope that's enough.
I know I get a few regen cycles, but every couple of weeks I'll hear the fan kick on after shutting off which I think means it was in the middle of a regen cycle when I shut it off.
