I remember that episode of Top Gear with the BMW X6. It was fun to point & laugh when the camera crew in the Land Rover made it up the grassy hill, but the X6 sat there spinning halfway up. I thought it would have been more fun to see what it would do if it had something close to off-road tires instead of the stock performance street tires. Still, watching it slide backward down the same hill with the back tires sliding and the front tires rolling (in park with the hand brake on) was kind of disturbing.
