Why do people act like *** klowns on the road.

A little story from a friend I've known a long time. They have deep in middle Georgia, like my family, although they are from south of here in the Byron area. Vic's (my friend) great grandfather was an insurance salesman back in the horse and buddy days. To tell you how BAD the traffic was......and still is in the Macon area, his great grandfather's insurance company would NOT cover anyone that went to Macon and if he found out any of his customers ever went to Macon, he cancelled them. LOL Macon is a total cesspool for stupid drivers.
Now that's Classic!
