Oh, that's brilliant. Let's leave 20 vehicle lengths between each
vehicle and reduce road capacity by a factor of 20.

You'd have loved the guy in front of me yesterday. I wish I knew
Morse Code, I think he might have been sending a message; I can't
think of any OTHER reason he'd have been tapping his brakes like that
on straight sections of dry road during the daytime, with no one ahead
of him.

Perhaps he had installed one of those asinine brake light flasher devices
one can find for sale by idiots who are absolutely *certain* they're a
safety improvement, even though they're not.

I wish you were around to see how angry sloth drivers get when they are
passed by me when I am riding the cannondale. You'd probably be amused by
it.

Not unless it was malfunctioning (which isn't unlikely), as the
flashes weren't regular nor did they appear to be proportional to
actual braking effort. It was more like he was tapping his foot
(perhaps to music?) on the brake pedal when he wasn't actually
braking. And I wasn't near close enough to be considered tailgating,
so he probably wasn't trying to get me to back off either.

Besides which, the reason for leaving large gaps between military vehicles
in a convoy has nothing to do with changes in speed. Soldiers are supposed
to train as they fight. The reason for leaving large gaps between vehicles
is so that a mine or (incoming lucky shot with an rpg) or WHATEVER hostile
forces action will take out no more than one vehicle at a time. If military
convoys were arranged in the typical "wolf pack" configuration of drivers on
a U.S. Interstate, one enemy soldier could take out several vehicles with
ONE shot. It would be child's play. -Dave

Sounds like the guy probably was a LFB (Left-foot braker). They tend to
rest their left foot on the brake pedal, even when they're not braking.
