I had an interesting idea on the ride home tonight; not sure if it's a good one or not yet. Maybe someone here has tried it already and can tell me. Or hasn't, but will be glad to give me an opinion anyway!
I was thinking about cars giving me adequate space passing on my left, which most of them were, but not all. I thought of sticking my left hand out a bit, but didn't want to remove it from the handlebar right then (working hard in a headwind).
Then I thought, instead of using my hand, what if I duct-taped a dowel off the left handlebar with an orange or red flag on it, as far out as I'd like them to stay? As I thought some more, I thought maybe a little flag by itself, waving straight back, would not be visible enough, so maybe I should add some silver tassles like they have on kids' bikes. More importantly, maybe I should use a length of spring instead of a rigid dowel, so if someone did hit it, it would give, instead of pushing my handlebars askew!
Good idea, bad idea? Legal idea? What do you think?
I can already imagine some cager claiming he didn't see it and getting mad at me for scratching his paint job.
