Well it all depends on weather not your any good at getting sideways and always bringing it true like Steve McQueen and the weather in your area. If its rainy or roads are usually wet, you probably want psm.

In So Cal, i dont have it and im glad cause i wouldnt want to have to turn it off every time i come to my favorite left hand turns on the way thru my short cuts that take me between the Valero and Texaco refineries where there are NO cars usually.

On second thought, if you dont mind turning it off when you want it off, it would be nice to have when you resell the car... option is an option.
