1. Get into a car, but have someone else drive it
2. hold a pencil to a piece of paper that is reinforced by something
3. As you go along let the pencil move as the road gets bumpy or whatever. You have to hold the pencil lightly enough that it’ll write but move when there are bumps or whatever
4. There. You have the signature of the road! Label it, and save it, or burn it…we don’t care.
