I'm planning a trip this summer with a friend and I'll be doing the driving. First time driving on the left. But more to the point, I have issues with heights. Drove alone along Route 1 on the Northern California coast two summers ago--managed OK in the beginning through some hairy parts, but discovered that as time went on I was more and more perturbed by the "cliff-crawling", especially when my side was the exposed side. I read lots of people mentioning this issue when I was planning the California trip, but haven't seen anything on this for Cornwall? Is the coastal driving not so bad? Or is it more of the same?
