I think the answer is self employment income but that is if your selling something and receiving money for it on your own time(not at a workplace)
Turning corners in a car takes longer, and all of the cars wouldn't go as smoothly because you need to slow down some to turn a corner. Since racetracks are ovals the drivers just need to turn, which you don't really need to slow down for.
so that people can help and send things such as clothes food water and also so the government can see the damages and help rebuild that city state or country
