Warm the engine driving or in the driveway?

Ummm....because Porsche says so, and they made the car.
Do you not have an owners manual? I'll take their word for it.

I think the point is that idling the engine is doing exactly jack for the drivetrain and its fluids. Idling til warm may make one think that the car is ready for hard driving, when in truth this would be extremely rough on the drivetrain. Gentle driving until warm ensures that everything is ready for high rpm driving.
