I've done donuts in my car with PSM off. How would this be possible if it was never 'really' off?

 

Super-mature as usual. You'll get far in life like that. Have a good one.

EDIT: Oh yeah, and another thing - I can contribute anytime and anywhere I want, so you better pipe-down or start a new thread for your inane babble.

 

PSM is much more complicated than traction control which in most cars only controls wheelspin. It has G sensors that will apply brakes when neccesary if certain g perameters are exceeded (this is the simplified version). when you turn PSM off, the TC part of it IS off so you can do doughnuts, but the G sensors (yaw is what they are called I think) still work if they think you are out of control, how this knows the difference between out of control and doughnuts I dont know.
