Forum Rider Down and/or notification of minor incidents

The single thing that makes you easy to see in some ones mirrors is a bright, flashing light. You pick it up in your peripheral vision. Even if I can't tell where you are or what you are doing I know you are there and can drive accordingly.

I'm not convinced this is the place, but may I add pedal reflectors to the list of things that are extra-noticeable when driving? Obviously only particularly visible when you're directly behind, so less relevant in congested city streets.
