Before you give them the one finger salute, just remember that they might be a new corvette owner and not know about the wave. I had no idea about it when I first bought mine. If you give them the finger they may think that people in older vettes don't like them because theirs is new and they won't want to wave to older vettes. If you just keep waving, I'm sure the idea will catch on. There are SOME people that are too good to wave and if we keep waving at them, maybe they'll get sick of it and buy a Ferrari, wait those owners wave as well...Lamborghini....nope, they wave...Civic. Maybe they will buy a Civic. For the others that know about the wave and just don't want too, well, I looked in my owners manual and didn't find anything about waving in there. So, it's too bad, but there is nothing you can do about it.
