I don't know what time the Auto Road folks got there that morning - but, it was early. The official start was at 3:30AM. But, the gate opened and cars started up just after 3:15AM. The cars moved through the gate quickly as they were processing 2 cars at a time. Driving up the cars were spaced out and it was not tight traffic. When we got to the fog we did catch up to a few cars in front of us - which was nice as that gave us a better idea where the road was.
I am sure people who stopped lower on the road had a good view as we did on the summit.
