I wave to 'em all - scooters, mopeds, bicycles - you name it. Waves are pretty cheap, and I've got a big ol' parcel of 'em to give away. If they don't wave back, that's OK. Catch you next time. The sport bikers often seem surprised to get a wave. They must think I'm on a H... Oh, you know.
I drove a tractor trailer for 15 years. Almost every truck driver would wave to other truck drivers. I hear tell it isn't that way so much anymore. Before CB radios became popular, we had a number of hand signals to inform the other drivers what lay ahead for them.
