It's videos like these that give people the idea that motorcycles, crotch rockets in particular, are some of the most dangerous vehicles on the planet. This camera was mounted on a Ducati 848 Evo and caught a Kawasaki ZX-10 slamming into the rear of a trailer that was slowing down to turn. The video seems a little confusing, considering there was a person slowing down behind the trailer and the hit looks like it was at about 50 mph, but it's possible there was another rider behind everybody. Either way, the result looks like it would have taken the life of the rider. Lucky for him, he escaped with just a broken leg and a broken arm.
