It looks like they've nailed the most dangerous 'slow' roads.
I've got a nomination for most dangerous 'fast' road-
The Capitol Beltway in DC. Bumpy as hell, cars coming at you from 8 directions at once (front l/r/center, both sides, rear l/r/center) and no telling how many of them have diplomatic immunity. I found going faster than everyone else cut it down to just front l/r/c. Only rode it once. Scared the #@%$ out of me.
