Well, I greet every oncoming motorcyclist by a gentle lift of my left eyebrow. 
(Ok, basically in earlier times I waved every other motorcyclist, but then we were a small crowd of non conformists, riding motorcycles. Today it's just everybody's hobby and there are too many out there. At some days, I wouldn't get my left hand back to the handle bar, as I could be continuously waving.)
When I was a student, I gave a lift to a friend of mine with my old car. While he was steering the car, he waved to an oncoming Porsche and the Porsche driver by surprise waved back. "Do you know him?", I asked. He replied: "No, but Porsche drivers greet each other." "Hm", I said, "But this is no Porsche and also you don't own a Porsche at all." "Also future Porsche drivers.", he casually mentioned.
