In line with the departure and a little to answer Eric's question, risk vs reward is always a factor. I ride motorcycles. I know the risks. I have been hit myself and was lucky enough to walk away. I used to ride with girls on the back frequently until I had a situation that convinced me that nothing I did would have prevented a passenger from getting hurt. Some moron dropped a ladder right in front of me at around 70 miles an hour. There was no way to stop and I was surrounded by traffic. I had to go over the ladder. If I would have had a passenger I doubt I could have done it and we both would have been dead. Risking myself because I like riding is acceptable to me. Risking the passenger is not. That same week I watched a guy go down on the highway at 80 and it was not his fault. I don't ride that road at that time a day any more, but I still ride. It's all about what an individual deems acceptable risk.
