YES, my ex's Mustang Gt for example. The traction contol is not LSD and as a result only one tire is pushing in a turn so BOTH REAR tires DONT BREAK TRACTION AT THE SAME TIME.

This way my mom can drive in the wet without going into a 360 spin in the rain. Believe it that posi will put you 180 degrees or more before you know it, because of this factor. This limits the car companys exposure and liability for low skill factor drivers and high power cars.
