Switzerland · measured from OpenStreetMap geometry
N21;21 runs 11.3 miles between Ollomont and Chamonix-Mont-Blanc. We counted 416 corners along it, which works out at 37 a mile — corner after corner with no let-up. It runs past mountain peaks, a mountain pass, cliffs and a river. That is calmer than two thirds of the roads we have measured in Switzerland, where the median is 53.2 a mile.
Ridden together with SR41 and 206 it makes about 23 more miles of the same kind of road.

How we measured it
Corner counts come from the road's own geometry in OpenStreetMap, not from ratings or votes. Every bend above a threshold of curvature is counted once, so two roads can be compared directly. Nothing here is crowdsourced and nobody paid to appear.
