A Bus Crash
Sitting on a roadside bench watching the traffic stream by, Mark notices a bus acting in a somewhat erratic manner. At first he is unconcerned as he has sat in the same spot thousands of times before without any harm coming to him, but the swerving bus is getting closer. The pattern of the bus does not change (this all happens within seconds) so he starts to rise and move farther away. His jacket is caught in the arm rest. Now he panics and desperately pulls away. Unfortunately for Mark, there is no time. The bus careens toward him, strikes him a glancing blow, and then runs into a tree about a hundred feet away.
