"Moth effect" - blinking or steady tail lights?

[Geonz]

... oh, and vehicles use flashing lights if they are moving slowly. A bicycle is (usually) a slow-moving vehicle, relatively speaking.
So... who's more likely to be sharing the road with me? A drunkard or a regular dude who might not notice one more solid red thing? 'Cause the basic principal could be that anything that attracts attention attracts the car of the drunk... but with that logic, I should try to be invisible... that's the strategy of an awful lot of riders around here, and I *don't* read about 'em being knocked down as often as it would seem, but I'm not sure I want to go that way.
(I tend to have both solid and flashing, myself.)
