I loved my motorcycle(s). I used them for commuting, for fun, for errands, but two things were always foremost in my mind.
1. A "fender bender" type accident can easily kill a motorcyclist.
2. "Motorcycle awareness" is probably not teachable. The human brain processes visual information somewhat predictably. The motorist's brain is scanning for dangers and threats, and that mean the brain is primarily recognizing automobiles and trucks. Put a pedestrian where he doesn't belong or a motorcyclist where he's not expected, and the brain is slow to recognize their presence. Add the current distractions of celll phones, IPOD's, MP3 players, and so forth, and you have a recipe for disaster.
So, when the motorist laments, "I didn't see him," he's not lying, and the wise motorcylist has to realize that he's somewhat "invisible" to other drivers, at least some of the time.
Still, when I hear my friends planning their next ride, I often wish I was going with them.
