I get cut off on my bike all the time by people with no blinker skills, I can't anticipate someone who doesn't signal. Trust me, if you are on a 2 wheeled machine and you get cut off, you will road rage.I only use my blinker if it affects anyone else. Probably 20% of the time.
All of you with road rage need to cool out. It ain't worth it, man. And, you're getting poor gas mileage.
