Well, we’re all a little competitive on our motorcycles, but the road is not a racetrack, and some people just carry it too far. You’ll recognize them by your ability to count their nostril hairs in your rearview mirrors. Waving them past is only a temporary solution, though. The only permanent one is not to ride with people who suffer from CPD: There will eventually be a gravity problem, or one involving two objects trying to simultaneously occupy the same space, that the whole group will have to deal with. Nobody’s got time for that.
