D10 — 三島市 to 伊東市
Japan · measured from OpenStreetMap geometry
D10 runs 23.3 miles between 三島市 and 伊東市. We counted 968 corners along it, which works out at 41.6 a mile — corner after corner with no let-up. It runs past a mountain pass, cliffs, a river and mountain peaks. That is calmer than two thirds of the roads we have measured in Japan, where the median is 53.1 a mile.
Ridden together with 413 and 521 it makes about 36 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.
