My wife and I do a lot of riding together... this year I have experienced more vehicles drifting into my lane than before. Usually the cager is eating a Big Mac or on the phone. I HAVE KICKED TWO CAR DOORS THIS YEAR TRYING TO GET THEIR ATTENTION!! Scary to be on a motorcycle and blowing my horn and yelling to get noticed and the cager never sees or hears me... Last week I installed a horn that sounds like an 18 wheeler and now they hear me... best money I spend on my bike ever !!!
