At least he isn't so immature that he addresses whining comments about
specific people to other people.

Coefficient of friction is the ratio of the force necessary to slide an
object at uniform speed on a particular surface to the pressure of the
object against that surface.  --Traffic Accident Investigators Manual for
Police, Northwestern University Traffic Institute.

Drag Factor -- the amount of drag that a surface puts on a tire(tires) on
a wheel compared to the weight on that wheel.

The drag factor with sliding wheels is the average CoF during the slide,
because (definition:above.)

Drag factor may also be used to represent the drag on the road by wheels
which are rotating but with the brakes applied to little to lock them.

ABS lets the brakes lock, then immediately releases them for a fraction of
a second, then begins to lock them again.  For this reason, most ABS
vehicles, under pedal-to-the-floor braking can be heard to squeal almost
as loud as regular vehicles, and will often leave light skidmarks.  Since
this is possible, the difference between that and a vehicle without ABS is
less than you might think.

Also you would have to understand that large variances in skid resistance
(drag factor) are equal to much smaller variances in speed.

Beginning to understand why this is usually doled out in a series of
classes?  (all of which EF has probably taken)

I am.  All the information above is in all the books I could locate on the
subject with minor wording differences.
