Administrative issue: youtube has taken down the video due to a copyright claim. Even if the version I posted was from Dutch TV. Dog gone it. So you will have to google it... sorry!
This video is very, very sobering. Jakob Fuglsang, a strong Saxo Bank rider, overlaps his front wheel with another rider's back wheel while hammering on the flats in a Vuelta stage. Loses control, swerves (thankfully not taking any other riders down with him) and slams into the back of a tanker truck parked on the side of the road.
And the guy walked away relatively unscathed and is attempting to continue riding the race.
So learn the lessons from this... be careful out there. And show anyone who says cyclists are wimps in lycra this video... the guy got a cut in his leg down to the bone, stitches and intends to continue riding...
