Who are you people? You "Non Wavers". I wave at anybody driving down the roads by our place, but not everybody waves back. Why not?
Troubles at home? Financial worries? What is it?
Heck, the Jeep owners even have a code called "The Jeep Wave". It might even be a law. If you are waved at by one Jeep owner and don't wave back, you could lose your Jeep.
Be friendlier. Wave.
