How the roads are ranked

Only the road's shape and class count, the same rule for every road and park. Each bend is measured by its radius in OpenStreetMap: under 30 m a hairpin, then tight, a bend, gentle; wider than 175 m is a straight. Streets signed 30 mph or less earn nothing. The stretch is cut where the bends stop coming. It is ranked on how bendy it is (55%), the class of road (20%: A and B roads in full, minor roads 70%, lanes 35%), how long it runs, up to 12 km (15%), and how much of it is inside the park (10%). One-way roads and roundabouts are left out. Nobody picks the roads by hand.
