I've been up there a few times. Leave your jacket on because you will see both warm, cold, and fog on the way up. Take your time and enjoy the route but if you pull off on the way up or down the pull offs sometimes slant towards the cliff side so watch when you come to a complete stop it will fool you.
The cars and vans will ride the center of the road so no real problem just watch the turns.
Here is a link of one of our trips up.
