Sense of Speed

Its not the old Cimino study, it's a more recent one, although it does cite that study.

It's a pdf of what appears to be a summary (really slides from a presentation), but it has data, references, etc.

Hi, Jordo!

Thanks for all your work. I think I remembered it as "Joan Cimino" when it was really J.Cirillo, but same data--that the drivers on the freeways were safest, had lowest accident rates, when about 10-12MPH over the median speed.

I think that the NHTSA presenter took the data and then carefully LIED about the findings. The data don't quite fit with their "overviews" and "conclusions."

In particular, they claim that the highest accident rate was at 2 standard deviations above median--but the curve--rate of change--was much steeper SLOWER than the median, and so the accident rate 2 standard deviations BELOW the median was higher and WENT UP the slower the speed at time of accident. They are so invested in speed as a cause--because, I submit, that it's easily measured and lucrative--that they can't grasp the truth and publicize it.

I'm going to keep searching for the original data. I'm a fact junkie.
