Heh. So I ride with mostly Harley guys though I don’t ride a Harley. One of the reasons we don’t wave back when riding as a group is that we use hand signals to communicate and waving looks like a left turn signal. As a result, we aren’t allowed to wave on group rides.

Secondary thing is that motorcycling is just a larger and looser consumer tribe than Harley or Yamaha or Ducati riders. Not quite as large as motorcycles + trikes, which is still smaller than bikes, trikes, and scooters. To some degree it is turtles all the way down in terms of how exclusive vs inclusive you want to be.

I personally don’t think there is anything inherently wrong with consumer tribes. The question is how does each one treat its members and newcomers and is it a healthy environment for everyone involved?
