Gawl. One of the reason I like to ride is to get away from all the BS of life. The CP connects you to the insane noise. I like to think I maintain my bike and carry enough of what I need to keep it going, that I do not need a CP.
Rarely do I ride so far away from civilization that I can't walk to a phone booth. Usually when out on a day long ride, I call my wife at least once- to say sorry, I just can't seem to find my way home. Be there soon with wine and roses.. Should I go out and ride the desert for forty days and nights, then I better re-think my ideas about communications..
I know when one of the wacko motorists puts me at risk, maybe I need a CP to call authorities. Just a risk I choose to take..
ps- Certainly a bike is more reliable than an auto, anyway.. That is what I tell my boss, when I commute to work. Couple times the bike has bailed me out when autos did not..either mine or my wifes'..
