I am both a biker and cager. So, I started paying special attention to this 'excuse'. And it's true; at least by my observation. It appears that one can better judge the approach speed of the wider car, than the approach speed of the narrower bike.
More, I have noticed that; where bikes have additional riding lights; arranged in a form of a triangle with the riding lights on the extremeties of the bike; judging their approach speed seems to be better and more accurate.
Combine the triangle of light with hi-viz, a white helmet, and lateral motion. Remain ready to avoid the pinheads who pull across in front of you anyway. I've been cut off while running code in an ambulance, so there's always a chance they're suicidal or something.
Some are guard dogs of the flock. Some are herders, search and rescue, or companions. We Devildogs are those, and also retrievers. Hell is our dogpark, our swimming hole. The fallen are our tennis balls. We don't leave the fallen behind, even if the master has to bring them home. Semper Fi, my friends.
