The above stats show that the highway is being radically under-policed
(or at least under-enforced). Only 0.007% of the traffic was cited, and
a casual observation of traffic on most any highway indicates more like
5% to 10% of the traffic is doing something that is "abnormal or
unsafe". A 100- to 110-mph speeding ticket for violating what you think
is an "unnecessarily low speed limit" is a perfectly legitimate ticket,
and there are probably one or two orders of magnitude more that 7
drivers per day on that highway that are going that fast.

That's highly unlikely. Using a median speed of 68 mph, a standard
deviation 7 mph, 100 mph is the 99.999997576 percentile speed (I
remember you liking a lot of digits after the radix point). This means
that less than 0.000242448% of drivers are going at or faster than 100
mph. Out of 100,000 drivers a day, it's less than one. Statistically
speaking, you'd have about one driver every 4 days going at least that
fast give or take. It seems that your estimate is at least several
orders of magnitude off the mark.

Arif's mathematical machinations to arrange a preconceived outcome.

A 20 mile drive on a freeway with that level of traffic, will usually
observe at least one car going that fast. In 24 hours it could easily
be one order of magnitude (70 or 0.07%) if not a lot higher, of the
total traffic.
