As a stock LC owner I will say that I wave at EVERY Land Cruiser I see.In my city I can’t swing a dead cat without hitting a LC or variant, but probably 80% of 200s I see are bone stock. Modified/lightly modified 200 drivers don’t often wave, but do seem to acknowledge each other somehow. On my morning commute I sometimes ended up driving alongside a guy in a black 200 with an ARB bumper (if I remember right) but never really interacted until he pulled up to my campsite at Cruise Moab to check if I was the same one he had been seeing and we had a friendly chat.
Long story short, I think stock 200 owners aren’t likely to be interested in waving or nerding out about tech stuff. Modified 200s may or may not wave, but they probably see you and acknowledge you.
There is a black 2013 I see every other day and guy pretends not to notice me.
I eventually gave up.
Wow man way to judge, check your modified 200 privilege!
