An evolutionary psychology domain-specific module

Attention, evolutionary psychologists: Evopsych researchers assume that back in caveman days we evolved various mental modules. I think I've found one that's getting ever more useful as more people talk on the cell phone while they drive.

I try to walk about three miles a day. The big danger in crossing streets on foot is that somebody making a turn just won't see you until he's hit you. This seems to be especially true for people trying to make fast right turns. When they are on the phone they are particularly unlikely to see you stepping off the curb. So, what I do when I see someone coming and I can tell he doesn't have his eyes on me is to raise my arm and point my index finger directly at the driver's eyes. His peripheral vision picks up my motion and some part of his brainssends to his consciousness a Code Red alert: "Awwwwooooggaa! Potentially hostile individual pointing weapon at me!" It gets his attention every time (although I wouldn't recommend using it in parts of town where drivers tend to be well armed and have itchy trigger-fingers). You should recommend it to children and the elderly as a way to making crossing streets safer.
