I get anxious when driving to new places, but am not very bothered when the area is familiar. Having a GPS device has helped too. But, the way I always explained it was that, if you take a wrong turn while walking, you can just turn around and go on the correct path. If you take a wrong turn while driving, you go way out of your way. Especially on the highway, when each exit can be very far apart. I'm not a huge fan of getting lost.
