lol I've stopped giving a hand to people driving Z's. Not like out the window wave but a raise of the hand off the steering wheel, or a flash of the beams and nothing in return. Z's arent too common in my area, especially in cold months. One time I had a beautiful Z park by and I walked by and said nice car... what kind of exhaust do you have? I believe he said " G, Ready" and turned around like I wasnt there lol. My friend who drove a Rubicon and other who drives an 04 stang always used to wave to fellow drivers. Idk, local guy who I've seen at starbucks has a le mans vert with a black bra always eyes me when I go in but nothing friendly lol.
