I was going to lunch today and was behind an Outback in traffic. Eventually I came up around and the kid must of seen me in the rear view because he was waving like crazy when I was alongside. It was really cool, he was genuinely excited. It was infectious cos I was waving and grinning like an idiot lol.
A few other times I've seen wrx drivers they've waved or flashed a thumbs up.
That never happened with the RX8 I guess RX8 owners aren't so friendly (except me of course).
