I do the same thing in the Jeep. LOLAlways. Been waving since August 1989 when I bought my first Corvette. Some wave back, some don't. It has always been that way. The funny part is when I wave automatically...when I'm driving my Yukon. Duhh!
I've been waving ever since I had my C-3 even though I haven't driven one in many years, Just a habit I guess.The "Corvette Wave" to other Corvettes is a nice friendly gesture. Been doing it for decades; plan on continuing! Not a snotty thing, but a friendly hello to fellow Corvette owners; even a short video clip (made during C6 generation).
