Ok Folks,
We have had some VERY different responses to this thread, and it's really taken me by surprise.
Abdul, I hope there is some tongue in cheek with your statement about this being spam. I personally dont see it that way, but I'll be more than happy to check with the other moderators and get their input.
The bit about waving to other bikes has got me a bit befuddled as well. A simple nod if someone waves at you is sufficient as well. No needing to take hands off the bars. I see it as if someone is that apprehensive about taking their hands off the bar for a second, maybe motorcycle riding isn't quite a good past time for them. If you have to feel that every second your on a bike you have to worry about everything, it's not fun....
