Please don't draft me out there without saying something and asking. I'm recovering after 11 weeks off from a crash caused by someone who was behind me. I don't like an unannounced tailgater, and rarely tolerate an announced one unless I know them and their skill level is up to snuff.

IMO, it's akin to hopping into someones car at a light and expecting a free ride. Against etiquette and rude.
