I'm kinda with the OP on this one. I commute on a hardtail with slicks and while every demographic - walkers, joggers, rollerbladers, cyclists, etc... - on the multi-use trail has their annoying faction, the roadies seem to give the least consideration. Very rarely will one warn me before passing, and I'm sorry, but I'm not wearing lycra so 4" is too damn close. How do you know I'm not going to randomly clip out? Despite what you may think, you're not going much faster than I am so I will be able to hear you say "on your left."
