Did that seriously just happen?

Imagine that you are at a red light behind a couple of cars. As you wait, the following situation transpires:

The passenger's door of the sedan directly in front of you opens and a small styrofoam cup and plastic spoon are dropped onto the ground and the door closes. Seconds later the driver's door of the F-350 that is next to the sedan opens and the driver hops down, picks up the cup and spoon and tosses them into the back of his truck. He climbs back in and as you watch, the truck inches forward and you can see the driver's head craning forward, apparently trying (and perhaps succeeding) to read the license plate number of the sedan.

Now, maybe I should be a little more environmentally conscious but for someone to feel such an inflated sense of self-righteousness to go as far as to pick up a piece of garbage and call the police about it has me far more troubled than the person who actually littered.
