I was biking up in the mountains last weekend. Crested a hill, motorcycle blew by me on the left, plenty of space no worries.

I moved into the descent, ~40mph. Caught up with the motorcyclist who was stuck behind some slow moving SUV's. So there I was on the right side of the lane riding my brakes. He was in the left, I imagine just in a low gear. Had a nice little chat screaming over the roar of his bike about how 4 wheeled vehicles suck ;-)
