Schematic for World Peace, Idea 1

I was driving yesterday, doing my best to make it across town and back home in one piece with baby girl, and had the following thought...  What would happen to traffic if people stopped thinking the world revolved around their own sphincter and began driving like their best friend's newborn child was in the back seat?  There's still going to be a ton of crazy out there, but I think it'd be one heck of a step forward in teaching people how to be polite when driving.  What do you think?
