OOH so its gravity. Going from what my buddy was relating to me, the appearence was that the wheels on ice were breaking and the wheels on concrete were turning. I was keeping my eyes out the window to see what was going on. Didn't even think to look at the RPMs. Kinda funny tough on level ground something was propelling the vehicle. My foot wasn't on the accelerator, and the car was moving forward. Don't know how to explain that. MAYBE YOU HAVE SOME INSIGHT ON THAT.
