This is self-induced exposure to being right-hooked. If you filter up behind a vehicle, (or overtake them in a bike lane) they're not too likely to notice you. What were they taught at drivers' ed when getting ready to make a turn at an intersection? Look left, look right, etc. but "look in the right rearview mirror to see if a bike rider is overtaking you?" Not when I took the class! [BTW, a good example of why riding in a bike lane can be hazardous to your health ... need to be ready to brake at all times]

As far as the definition goes, I'd agree with Bekologist.
