I wonder how much it is like an aircraft - many many many dials and knobs, all with there purpose, but only a few needed in normal operation, or used once or twice a trip.
I assumed the purpose on an aircraft is a bit different: you don't want a "check engine" light to go on when you are 10 miles from the nearest landing strip. Probably a bit more detail is useful when a stalled engine means 50% odds of survival.
It's more of operating vs using, we had a CUT and there were situations where you want the control(diff lock, split brakes to turn in-place, etc).
Hydraulics and attachments open up almost an endless possibilities.
