I dunno - i find the compass extremely useful, particularly on the numerous poorly marked roads round these parts. I get on the road, on a rainy night trying to find a new address after meandering around twisty roads. I know the roads runs say E-W, and i want to go west. With the compass i might save myself a lot of time and aggravation knowing which way to turn.
You are already more advanced than most drivers -- you know which roads run E-W....[;)]
