Both motorcyclists and those that have never ridden know that riding one on the open roads is fraught with danger of serious or even fatal injuries. Besides the inherent danger of motorcycling too many riders are not properly trained and too often are inattentive in a situation that can be merciless if you allow your mind to stray. It's bad enough in the US but take a look at this accident in the PRC. Both the driver of the truck and the motorcyclists are totally clueless on what they are doing or should be doing. In this case the motorcyclist appears to emerge with injuries that are probably serious but it could have ended dramatically worse for him. ADDENDUM: Notice that not only does the truck driver appear clueless to the bike but also to the car coming the other way down the street.
