I stumbled across this and any scary road might be interesting on a bike and fun in a car…
America’s Scariest Roads
Highway One/Big Sur
California
Alfred Hitchcock could not have conjured a scarier highway—122 miles of vertigo between Monterey and Morro Bay. Two lanes for nearly its entire length, the road meanders along cliff tops poised high above the Pacific, including 33 bridges and countless drop offs into liquid oblivion. Anyone faintly squeamish should not attempt to drive this route.
