First, I have to give credit to Naffantait, who actually came up with this amazing means of making huge amounts of money in Gran Turismo 7. His video is linked below, and I highly recommend you watch it because he gives other methods of making huge bank in as little time as possible in this video, and has numerous other videos on other glitches and shortcuts. Check him out!

I am simply expanding on a few aspects that make it a bit easier for people like me, who aren't super gods in this game. If you're looking to grind for credits, this is a nice relaxing (and very lucrative) way to do just that.
