Am I the only one who secretly wants a Cayenne S?
...I promise that I'll use it 'properly'


As for the gravel thing, any truck/car/SUV with decent tread on its tires will easily fling a rock 4 feet in the air. If you do this in front of someone (like passing and returning to the right lane) they will drive into it. I've seen it happen, and it's happened to me. When some sled-neck in a 35" mudder-shod Chevy flings a ping-pong ball sized rock at your face at 60 mph you tend to start thinking about such things.
