Hey Dirtbikedude, I've had a few experiences along those lines with a little twist. I pretty much ride the same roads dressed the same way ect. but have alternated from a mountian bike to a road bike. While riding the mountian bike, to other rodies you would think I was invisable! Yet while out on a road bike, these same riders the very next day will pass you going the other direction with a smile and a wave... Go figure! (Shakes his head).
