This thread seems to have morphed a bit from the subject of other peoples' reactions in general, to the issue of who waves back, and whether some particular bikers who prefer certain makes are more or less polite/responsive than others. My thoughts, after returning to biking following an extended, 40-year absence:
The Spyder sure is different, both in looks and appeal. It's going to evoke a reaction, and not likely to be ignored; all owners should be prepared for this, one way or the other. Most reactions are positive, in our experience - about 98:2. Old folks are amused; kids are really delighted. The bike looks like it stepped out of a cartoon, so what's to be negative or un-pleased by it!! Mostly we get asked: "Is it comfortable? Is it fun?" To which we say: "Absolutely, go buy one!" By and large, everyone smiles. There are always two jerks, two downers in every crowd who will never change, and don't want to know any different. Leave them be; their loss.
Waves and nods: I had to get used to waving back, to re-learn the 'courtesies' of bike riding after so many years of cage driving and threats from road rage personalities more inclined to hate than like. "Oh yeah", I told the wife, "bikers do wave at one another. It's the custom for one 'Knight of the Road' to salute another when meeting". So, we wave; we don't get pissed if the other guy doesn't wave back. But, we do notice. It is a kind of courtesy thing, a gesture of respect from one rider to another, simply for braving the elements and taking the open bike out into tough territory where other, much larger predatory beasts roam. We all face the same hazards; all of us should try to be respectful, even when 2% act like jerks; we'll survive better in spite of them.
A quick story about the greatest wave I've yet had from another biker. Last weekend, we rode Hwy 507 in Ontario, long reputed to be one of North America's twistiest rides. It has seen more than it's share of fatalities, cars as well as bikes. We were northbound, at fairly sedate speed in tight turns with dips and climbs, when out of nowhere, coming downhill, south, left curve, very fast, was a green two-wheel rocket with a biker in at least a 45 degree lean; any lower and he would have been scraping a knee. I was simply amazed; he waved before I did. When he dropped his left hand, two fingers down, I could have sworn he almost touched pavement. I took his wave as an immense token of respect; just taking his hand off the bar was amazing. A nod would have been more than most would have even tried. He had my respect back a thousand-fold, not just for the friendly gesture, but also for his riding skill. He was calmly in control throughout - almost as if we had simply walked past one another and smiled on a quiet village sidewalk. Cool!!!
A respectful wave to all; safe ryding folks.
