Well sodomy by way of motorcycle certainly looks unpleasant. I mean, what the fuck was the guy on the motorcycle looking at? From our vantage point it would appear he had the opportunity to see these cyclists from at least 20 feet away. I don't know, maybe the sun was in his eyes?
According to the description on YouTube:
Rider hits cyclists coming out of a turn on Mulholland Hwy. Cyclists didn't appear to have serious injuries. Note about cyclists and riders coexisting on this famous 2 mile stretch of road. Even though bicycles are up here in increasing numbers, this is the first time a bycycle has been hit by a motorcycle In the fours years I've been up here. Motorcycle riders of all skill levels come up here to practice. This location it is pretty common for riders to sometimes go wide exiting the turn. It is very unfortunate, and a rare case of being in the wrong place at the wrong time.
