The last time I rode down from San Francisco Route 1 from Big Sur to Cambria was closed to car traffic. It was heaven!!! OK yeah we had to hike the bike at times due to slides but no car traffic!
You might still encounter slides. Deal with them. But frankly your worse problem will be seniors driving motor homes on a narrow, winding, steep Route 1. Fear for your life...
