Human nature - people love to travel in packs, whether they realize it or not. You'll have 50 cars in a 25 mile stretch of remote & far between cities open road, and there goes a clump of 6 or 8 or 10 of them doing 70 all 12 feet apart.
One of the reasons I like doing 5 mph over - I stay out of large packs and I generally maximize the time between packs.
