I know of two people, one that was killed, and another very very seriously injured on bikes in accidents which were not their fault, accidents in which they had no chance to avoid their fate. The roads are full of drunks, illegal aliens, and distracted drivers and if I have to encounter them, I like to be surrounded by some airbags and a metal frame.
I can only say two things.
#1 is - Head on a swivel.
You're right that there are a lot of people on the road that a motorcycle rider needs to beware of.
#2 is - If it's your time and G*d calls you home it doesn't matter if you have 2 feet of metal with airbags all the way around.
You will go if the good Lord calls you home.
My biggest fear is dying on the sofa, watching TV.
Look, I'm all for managing risks, but you gotta get out and do some stuff.
If the good Lord sees fit to call you home, at least you did some stuff.
