Drive really fast, get sideways in the corners and all you will be concentrating on is the road, not the drop off, LOL.
Actually, paving the road all the way up has been a source of deabte for years. On one hand if it gets paved, there goes the dirt road attraction of the annual "Race to the Clouds" hill climb. On the other hand, it would be safer for the tourists and better for the environment in preventing errosion.
