They are public highways. There will always be people doing different speeds. Just this weekend I was hauling my horse across the state. I was doing the speed limit or below. I had to accelerate very, very slowly as to avoid injuring the horse. I had to take turns very, very slowly as to avoid a tip over. Horses are very top heavy and they move....It is very easy to flip over while hauling a horse. Also, I cannot hit a massive pothole or other road mess without possibly injuring my horse, so I need to travel a bit slower than I would with an empty trailer.

People were cutting me off, passing me with almost no clearance, and tailgating me. This is what was dangerous. I was always in the right most lane and traveling very predictably, yet some people get so frustrated at the slightly slower speed that they are fully prepared to kill someone(and my horse) than to be a little patient. These are the people who are dangerous, not those of us who on occasion need to travel a little slower.

The keeping up with traffic argument is weak. So, what if traffic is traveling at 100 mph...should I keep up with that....then what if 100mph becomes the norm and everyone needs to travel at 120 mph to feel like they are getting somewhere. Do I need to travel at 120 mph to keep up with traffic? It is some bizarre psychology that whatever the speed limit...people feel the need to go 10 -15 mph faster.

Let's face it if everyone followed the law and limits to the letter there would be no accidents. Accidents happen when someone does something they shouldn't have done(like not pay attention.) Humans have a limited ability to respond. The faster you go, the less time you have to react and the greater the chance for error or collision should things not go exactly as planned(like a deer runs in front of you).
