I suspect you could do it with something like the following: highway= primary & (width=narrow | width < 2 | est_width < 2) [0x04 road_class=2 road_speed=3 resolution 20] highway=primary [0x03 road_class=3 road_speed=4 resolution 19] (This would demote a primary road to the equivalent of a secondary.) I, however have not tested this, so I cannot confirm if this would work. Cheers.
