Wow, he's got some balls. Hope the truck doesn't brake or swerve suddenly.

Years ago I heard of a truck driver being examined by an instructor for his road test. The trucker was going down the highway when he noticed a Cadillac sneak in behind him, he could no longer see the car as it was too close to his rear end to be visible from the rear view mirrors. Once in a while he could catch a glimpse of the tail end of the car as they went around some shallow curves but the drive was tucked in tight drafting the truck and trailer. Well the trucker spots something fly off a flatbed ahead, it's an engine block, he glances at his instructor who doesn't say a word, the only thing the trucker can do is to straddle the block which is smack in the middle of the lane. They pass over the block without contact and look into the mirrors just in time to see the spray of parts fly off the Cadillac as it plows into the engine block utterly destroying itself.

It wold take considerable less than an engine block to completely wipe out this guy on the bike.
