Drive By

Ever since I started running consistently, I have been annoyed and intrigued by "the drive by." I am minding my own business, jogging along the street, and occasionally people (okay, males) whistle, honk, yell etc. One time a guy was sitting on the sidewalk and pulled out his phone to take picture!
I do not understand the logic behind their shameless expressions. I am sweating, gross, and trying to maintain a steady breathing pattern, so I am surely not going to respond to the brief, shallow, shout-outs. And you, the guy in the car, are driving faster than i am running (though some do reduce their speed temporarily) and will not actually gain any reward for trying to catch my attention as you pass.
So for the record, I know a friendly honk when I hear it. All other horns, whistles, cat-calls or pet names (namely "baby") are not working to your favor.
