Buses and motorbikes don't mix (graphic)

On my night bus from Da Lat to Ho Chi Minh City, I saw a man lose his life.

It was about 11PM and I was amicably chatting with the Coloradoian across the isle. I looked up to see a lone headlight to the right side of the bus swerving left, but not soon enough. Our bus driver honked and slammed on the breaks. Screech, crunch. I looked out the window and saw a Vietnamese man laid out on the pavement. It was a horrific scene. My chat buddy's friend is also a WFR, and we talk about what we might be able to do to help. We get out of the bus and join the throng of people standing at a safe distance and staring in disbelief. We ask by miming if anyone has checked for a pulse. They have and there isn't one. The other WWOOFer checks too, but he told me when he reached for the wrist on one arm, both his bones were protruding from the skin. One leg was twisted at an odd angle, betraying a probable femur fracture. The motorbike was imbedded about 2 feet into the left front corner of the bus. I wonder if he had been wearing a helmet if he would have had a chance?
