I stand by my earlier statement. If you're using a paper map in a city centre, you're an unguided missile waiting for a target to impact against. That goes for you, me, the bloke next door, and Midchuck as well. I'd rather my processing cycles (to use Greg's phrase) were more dedicated to paying full attention to the road and other drivers, instead of having to second-guess the next badly-set-up junction system. This is even more critical in Europe, where towns were set up for people driving oxen, not cars.
