Twats on mopeds

I'd be happy with an "I am become Death, destroyer of worlds" sticker from Tynan to attach to the offending vehicle.

If we had say a pad of these somewhere easily reached we could tag vehicles in a non-damaging way so that other cyclists would be aware of the danger posed by the driver.

I vote everyone buys reading specticles and learns to make this expression. A quick tap on the window and an implied facepalm, should have the desired impact.
