One of the rules for flying ultralight aircraft is that you are not to fly over gatherings of people. Because that could be seen as two or more people I try not to spend extended time above things like roads. Using an S turn to cross a road gets me from one side to the other while ending up traveling the same direction at the start and end of the manuver.
