Hm there are a few types of vehicle ways (highway=residential/living_street/pedestrian/service/cycleway) which present high usage by non-vehicles, so I think it would also make sense if the renderer also checked for these values: - mtb:scale=0 - sac_scale=T1 - wheelchair=yes/limited
Which, of course, could be checked for any other kind of way, but especially for these kinds this check seems important.
