a) because distinction between physical and legal barriers is important. Ok in that picture there is no much difference, but as Simone pointed out, for long roads there is a big difference: if any router can't distinguish between physical and legal barrier, it will not suggest to emergency vehicle to cross the line, and it will tell them to do a long alternative trip instead. This is a big problem, because when you are driving the GPS shows you only a little portion of the route and you may not understand (especially in emergency) that you can shorten the route simply crossing the line. Moreover if we accept solution b) we should tag every road with continuous line in the middle as two separate roads, one for each direction. >Additionally to the lanes=4 and oneway=yes you could put a divider-tag on the way http://wiki.openstreetmap.org/wiki/Proposed_features/Divider >even if it doesn't explicitly tell you where the divider is placed you might be able to infer it from the following ways (at least in this case). +1 We can improve this proposal, to make clear where the divider is placed.
