Lately it seems that people don't practice standard hand signals when cycling. No, I'm not talking about the fact that we mostly don't signal at all, but that when we do, many of us are doing it wrong.
It started a few weeks ago when I was on a tour over in Ontario, Canada. The guides were using their right arms outstretched (as in a pointing gesture) off to the right to signal a right turn. I thought, WTF, but chalked it up to a cultural norm of a different country.
Then I saw that to signal a stop, they used their left arm in at an upward right angle with a clenched fist, like our USA right turn signal! I got the possible military roots of that one, but it all seemed silly and stupid to me and another American rider, and we took to chuckling and flailing our arms every time they signaled.
Then, I started noticing a couple of riders in my very home town doing that "I'm-pointing-to-the-right-with-my-right-hand-and-that-means-I'm-turning-right" gesture, and was really vexed.
What gives? Do they do it differently in Canada? Is it just a Michigan thing that I think is standard? Is it not taught in Drivers' Ed. anymore?
