Another issue: In my experience, in north america, navigation is more focused on compass points (take Road XYZ north, southwest, etc) whereas in Europe it is more focused on semantic directions (turn right on highway towards Groningen). The european way allows for easier verification if the road is actually the road you want to take (as in: do I really want to drive to Hobbington? The street sign says I should take the second exit, so I go with that.
