I think this is the wrong way to look at this. If you rely on routers to make this kinds of decisions, you are going to have a lot of problems. What if there was a roundabout island where you were allowed to u-turn? You should put in a "allow_roundabout_u_turn" or something. Also, some routers are not going to have the same logic. Anyway, if you don't put a "no_u_turn" restriction in this case, routers are rarely going to route through that, so I think we are safe either way :) Janko
