About 1,800 Roadsters in the U.K, 150 at the most are members here. In the 18 months I've been on this board I have seen just 2 members cars, outside of meets of course, and maybe 50 or so other Zeds so the chances of spotting a another forum car are slim. Doesn't stop me from waving or flashing though. Don't know when this tradition started, but I can remember AA patrol motorbikes waving at you if you had an AA badge on the front when I was a kid in the 60's
