Yet another case for tagging defaults on admin boundaries. Having "no U-turns" by default seems to be hard on navigation software - it is not a trivial task to recognize U-turns from other turns. On the other hand, the number of cases where navigation actually has taking a U-turn in its best route will be small. -- André Engels, andreeng...@gmail.com _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
