I think it started some years ago when some news report claimed that cars were getting hit and pushed into other cars or worse yet into intersections, where they got hit by other cars that were going through the intersection. They claimed if motorist would just leave a few car lengths between cars in front or intersections there would be fewer deadly accidents. Not sure if it is true but I guess it doesn't hurt.
