I have no idea what they are (ARE NOT) thinking. Like you said, they look right at you and continue on their merry way ! ! ! ! ! ! I know I am in no way invisible with the bright yellow jacket, red motorcycle and super high bright auxiliary lights. I was trying to think of anything that made sense as to why someone would do that and I can think of nothing. Unless they think we are a bicycle doing 5 MPH. Even those you can not stop on a dime. But even bicycles are supposed to be treated like a car on the road, which I find ridiculous because they have no features that make them even close to a motorized vehicle (speed, acceleration, lights, horn, etc.) so I still would have had the right of way. You just gotta keep looking and expecting the worst most of the time and figure how to get out of any situation. Sheesh !
