48.2Per mile

D 41A runs 12 miles between Vovray-en-Bornes and Bossey. We counted 578 corners along it, which works out at 48.2 a mile — corner after corner with no let-up. It runs past cliffs, mountain peaks, a ridge line and a mountain pass. That is busier than two thirds of the roads we have measured in France, where the median is 26.9 a mile.

Ridden together with D 41A and D 909a it makes about 12 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.
