It is useful as a plain paper map. As long as you don't let yourself be lead
by GPS at all times, it is not really important if the road is placed exactly
correct. Als long as you have junctions and road numbers, you'll get to your
destination.
It is when you start using a GPS to lead you and it tells you to turn left
because it thinks the road is some 3 miles to your left when this map is not
useful.
