Barbie Jeep downhill racing is so cool! Everybody I show this to gets totally sucked in. You can't really tell from the video, but I'm guessing that hill is really steep. Watch long enough to see the guy standing up on the quad. Would you ever try this?

It appears to me the skill in this comes from 1) choosing a high quality Barbie Jeep. 2) using your weight, not your legs, to steer down the hill. The contestants with the most skill in shifting their weight seem to win every time. And with the high rate of wipe outs, I'd say control is more important than speed.
