yes use of term 'cager' was designed to grab attention. i am such myself; in fact, I drive a hulking V8 sedan (though only 5,000 miles this year vs. 20,000 last year)

yes the title is a play on RS. but if they are the devil, so am I. truthfully, I find myself nervous driving alongside cyclists and almost ran into one once even though I was trying hard to pay attention (it is a particularly tricky intersection in Boston, and I think the non-cager ran a light).

I can't agree that it is self-defeating to wave cars on or say thanks. many motorists think of us as oblivious, self-centered/righteous, and flagrant violators of the law. I think that's why they get mad, at least as much as because we slow them down.
