This seems like a poor plan.
It is indeed a very poor plan. Almost all major streets in danish cities have biketracks in each side of the street. In profile, the construction looks like this: sidewalk ------------- \ bikepath --------------------- | heavy traffic. ----------------------------------- When mapping a crossing of two such streets, you need to make the following construction: . | . . | . . | . .....................o....|....o.................... . | . --------------------------o------------------------- . | . .....................o....|....o.................... . | . . | . . | . That's five nodes for a single intersection! You can imagine how many bugs there are in the maps where mappers have not had the patience to do so! Mostly, mappers have just "forgotten" the connecting nodes, which doesn't matter much for map-drawing, but screws routing up badly. It means that the map in danish cities has gazillions of "intersecting ways" validation errors. Another thing is that you need to place the parallel cycleway about 20 meters from the highway to have it rendered on the map. And mappers have a hard time constructing a parallel cycleway, they often zigzag along the main road and it looks terrible. I know Jonas has some examples on how nice it looks when you use the cycleway=track on an osmarendered map (mapnik doesn't use the tag). Perhaps you can post those as an illustration, Jonas? PS: In fact there's a similar problem with sidewalks. There ought to be a "city_street" highway type with sidewalks.
