My dérive starts with the first decision I make turn left if the first person I see is a man and turn right if the first person I see is a woman. This led me to go left to start the dérive. Recently during the fall, the different colors of leaves on the tree gave me the idea. Yellow leaves tree means to cross the road; green Leaves tree keep going; no leaves tree means to turn around and go back.I also found many people were wearing hats, so I decided to turn left if I saw a person wearing a hat. I finally get to the nearby park, and there is no road limit. It gives me the idea that if I see a person walking with a dog, I walk across the grass instead of walking along the road.
For the whole dérive process, I took about 1 hour on my own on the street. The process ended because I felt too tired to keep walking.
