The engine doesn't return to idle until one let's off. You won't be letting off, not at highway speeds. Too much momentum in that trailer as it's swinging thru its arc.

One won't be releasing the throttle OR the TT brake for a fair distance (related to initial speed, etc) as horsing that trailer into alignment AND keeping it there continues through making an emergency stop on the shoulder to inspect the rig.

If one were taught the stupid "rule" of right foot braking, now is the time to change. (It's more exciting with a clutch, 'cause then one wants to know heel & toe method for simultaneous throttle and brake feathering. And how to downshift in such an event to keep the engine from stalling).

Keep your foot OFF the service brake.

Given no mechanical failure, the point at which to use the service brake is a ways down the road.

And hit the four ways as soon as you remember it.

But there's not a split second to lose initially.

Ok, if you can design a purely brake based anti-sway system that takes care of sway with no feedback, there's big money in it. Every brake based system I've ever seen needs feedback.

I believe we're talking past each other.

What I'm talking about is inherent stability under braking. Rather than active stability correction under braking.

An analogy would be on a solo vehicle, brake bias vs. ABS. Under the limit braking vs. over the limit braking.

The former maintains composure and stability when bias is correct, to mitigate sway. The latter actively corrects sway once it has set in.
