I would take about 75 ft more to stop a car traveling at 80mph than at 70mph. About 50 ft more to stop a car traveling at 40mph than 30mph. I'm too stupid to do this kind of math, see it here...

My point is that 90mph really isn't "almost" 100. As speeds increase, these 10mph differences are worked on increasingly harshly by physics.

Edit: FWIW, the stopping distance for 130-0 is about twice that of 90-0.
Well if we're talking stopping distance I think you and your M******* commuters doing 90 all packed together down the highway is much more dangerous than 130 by your lonesome.

Just kidding, it's the same way in CT. Go with the flow or get pushed off the road.
