Ha ha I don't wave at scooters either. I don't know why really, I just don't. Everyone else gets a wave, but with Harleys I hesitate to see if they'll wave first. I guess I could trade my waves in that I would give to those few Harley riders and apply them to the scooter riders. I should really only share waves with those who will actually wave back. Oh and my pet peeve is when somebody waves from the other side of an interstate highway, particularly those divided by huge medians. I appreciate the effort, but seriously, why bother in that scenario??
