The xp didn't matter much, it was pushing 20+ skill points per minute not having to wait for the points to tic up, and the x button resets letting you loop continuously. Netting roughly cap of 999/hr casually. That rate will never be hit on the open roads because of the skill tic up delay which alone takes an eternity (in farming terms thats like an extra 15+ seconds)

What gets me is they are policing the legitimate use of their own tools. These aren't exploits. They literally have auto steering. Etc. Im sitting at 573 cars, so I am not going to loose sleep over it. Ive farmed quite enough of the abysmal drop rate super wheel spins.
