All I could remember was driving along a certain route, and making a U-turn. As I made the U-turn, I noticed that I was at a dead-end, and was told by some construction workers to go up a steep road, much steeper than Lombard Street. And much much steeper than the link.
I had to carry the vehicle with me, on my shoulder. Surprisingly, the vehicle was light enough for me to carry. After climbing a few steep areas, I was able to go up, and reach a level road. I placed down the vehicle, got into it, and drove away.
