There is a weaker version of 7: using gold to restore drive and service the cars instantly, but posting WTTT times with properly bought upgrades only. It is an exploit in that you don't wait for drive to fill, but weaker in that, at any given time, you could be able to repeat or even improve your laptime.

This would tie in nicely with cloud restoring for gauntlets. OK, maybe this is number 1.
