You'd be surprised how quickly they stop - even loaded.
First tests are with an empty semi. 80 kph / 50 mph
Then they load it up to 40 tons - max. load in Germany and France.
At the end of the clip, you get to see why they stop so fast.

You have more reaction time following a big rig closely

than you do following a porsche 911

The 911 has formidable brakes, and will out-brake just about anything.

or a motorcycle at normal distances, as each of these vehicles can out brake you.

It's yet another urban myth that bikes brake better than cars.
They don't.
Even if you put a seasoned racing biker at the controls, sportsbikes still get out-braked by run-of-the-mill family cars.
A local bike mag put on these tests some years ago, and were surprised themselves.

The most valid point, against drafting is the one about smashing into something the rig was able to high center. Using a CB to communicate with your draftee is a very good idea and helps address this concern.

It won't nearly work as quickly as needed.
