Texas highway would be the first to allow 85 mph speed limit

57. Your 'basic safety rule' doesn't make much sense

Maybe it's just the way you tried to describe it.

"The safest speed to travel at, regardless of the posted speed limit is that speed which 75% of the traffic is flowing."

But you will never get 75% of traffic travelling at one speed.

"Where speed disparity has the greatest effect and therefore causes accidents (regularly, I should add) is when someone is traveling outside that 75th percentile, either well higher or lower, and yes, 10 mph is enough to pose a greater risk."

99% of people drive "outside that 75th percentile", by definition. You can measure a speed which one quarter is driving faster than, and three quarters slower than. But when you try to make it a 'rule' to drive at that speed, which much of your post seems to say, then you will inevitably be asking more people to speed up than slow down, which is more likely to increase speeds - including that target speed. However you came up with your 'rule', I cannot see it as decent advice to others.

I do agree with you about people staying in the right lane whenever possible (or, for me in the UK, the left lane - the rules of driving are clear about it here, and most drivers are a lot better at following them than in the USA - I hated passing someone on the left of a 3 lane highway, trying to pull back in front of the car I had just overtaken, only to find someone who had just 'undertaken' them on the right trying to pull into the same space I was going for - when I couldn't see them because they were hidden by the car I was overtaking).
