Oops, my question was ambiguous—I was actually wondering how you measured "mental load", as you put it.

Ah, misunderstood :).

I've been doing the same ~7hr drive + workday for 2 years. Both myself and my wife noticed I was a lot less wiped out after AP. We have the car ~3 months before AP so it was a pretty controlled change.
