And I don't exactaly understand by "a drivetrain that doesnt have a direct motors to wheel system" -- do you mean a shifting transmission? or some drivetrain that transfers power to the wheels via viscous fluids?

I mean like on a car. i believe its because of the toque slipage something or another. Basically its the reason you can have RPM stay the same even though your car increases in speed. im not real familiar with the mechanics of cars but ive been going into depth with a cars drive train and its really nice!
