i chuckled. do you use gps?
GPS only makes it worse. It turns out that interpreting an on-screen map takes a non-trivial amount of brainpower that should be directed into safe driving.
Comparing my current location to maps in real time (or even alter on when I look at where I've been that day) helps me expand as well.
And to be fair, interpreting an on-screen map takes up slightly less brainpower than a paper map. This is really important since I'm the type that can get my bearings messed up by going in and out of a gas station. I have no real sense of direction and have to work really hard to have what I have - and always have.
