I dunno, I’ll wave back at anyone who initiates. Believe it or not mostly CJs and a few old Landrovers wave more than anyone. Quite honestly I’m starting to grimace at the new Bronco owners as much as the new keep owners. Same breed, different vehicles. Obviously there are exceptions, but I’m speaking generally.
I kinda get the same vibe. I'll wave back to anyone that waves. When I'm in the 66, I'll throw a wave, peace sign, shaka, or nod to just about anyone in a cool, old car, including FJs, Land Rovers, and even the old van crowd (VW, Dodge, Econoline, etc). I joke with my wife that driving the Bronco is less about "driving" and more about "operating", so any car I see on the road that looks like it needs to be operated gets a nod.
I've been driving my Bronco a bit more lately and see a lot of new Broncos on the road. It's kinda rare for a new Bronco owner to wave, though, I also don't initiate a wave to new Bronco owners. Other than the name, they're just not the same. Though, I will nod to full-size Bronco owners. Maybe it's just a lineage thing?
Most of the waves, nods, and thumbs-up I get come from
old guys -- ha, who am I kidding? --
guys my age and older driving regular cars, on Harley's, some other classic car, or just any Ford truck.
