I spoke with Commander Dengler (sp?) of Zone 4 about flagrant, maddingly, seconds late red-light running on Penn Ave. I asked her about citing drivers by mail given only a license-plate #. They have done this for crossing guards (who I believe are empowered to cite drivers directly, not sure why they don't). She was concerned that the driver himself needed to be identified (not entirely true) but I figure that even if the owner wants to go to court and argue "it wasn't me driving, it was someone else", there's an official legal record, and the owner is put on notice that society cares.
The reason I was emphasizing red-light running is that I think it's on a continuum with road rage. It's self-centered, bullying driving, motivated by a sense of entitlement and complete disregard for the rights (of way) of others. I would be willing to bet that the road ragers are also frequent red-light runners.
