Racetrack Ideas

This thread was made for what purpose?

 

QFT

Both of these have been done already, the roller coaster one numerous times. In the amount of time it took you to make this thread you could have used the search bar and found maps like these instantly. There is no point to this thread.

 

A parking lot does sound like a cool idea but there isn't much you can do with that idea.
