When I first got my driver's license, back in the dark ages, someone told me "Drive like everyone else on the road is an idiot...because most of them are." The point was well made. I remember an incident, shortly after I got my license, that clearly illustrated the concept. It was 1977, I was 17, and driving my mother's Buick Electra -- that was a huge car. My mother sent me to the supermarket, and what happened on the way back ... There was a long stretch of road with no businesses, and no side streets. Just an old dairy farm to the left (it's a gated community now) and some houses on the right, but set back far from the road and concealed by trees. You really felt alone driving on that road, unless there were other cars around (these days there are always other cars, but back then, not so much...) Well, I must have done something to offend another driver, maybe I cut him off as I came out of the parking lot, because he made it his business to get in...
