I had a thought yesterday to wake up those wonderful people on the road whilst fighting your commute. When someone isn't paying attention, eating, cell phone glued to their ear, putting on makeup etc and have almost ran you over.
Whip out that can of silly string and have at it while next to or in front of them. They'll think your bike is either being over friendly or melting. Either of which should wake them up that they're drive a 1-1/2-2 ton plus vehicle.
If you're very artistic maybe even spell something backwards on their windshield?
