These are some of the best explanatory presentations in existence. I would love to see them analyzed to better understand how they are so effective.

Eliminate jargon, simplify as much as possible... but no more. You can explain almost anything to anyone, if you recursively apply this technique.

Is an excellent lemma. Applying it, of course, is what's very difficult :)

It's very 1950s military.
They never mention that this is a simple feedback control system. The mechanics that maintained the thing had to know that, since it's vulnerable to the oscillation and lag problems of a simple proportional control system. Those feel like steering wheel vibration and slop to the driver. This is for an off-road heavy truck, not a sports car, so a little lag is not so bad.
The very large vehicle at the end is the M65 Atomic Cannon.
