So since I've had mine (January) I've seen exactly 3 through my first 7,500 miles. Then leaving work yesterday I see one behind me on the highway. I slow up to get next to him and the dude doesn't even look over. Then today, on a seven mile ride home from a ballgame, I see two in a matter of 3 miles. Both coming at me in the opposite direction. I waved at both but didn't see if they even noticed.
