Plus in Europe it's forbidden to tow with a rope like he does. You must use a rigid link, like a bar or a tube.
But like speeding as long as you show decent discretion when doing it you'll be fine.
You just need to press the brakes harder. Like 3 times harder, not 30.
If you park in a slope and turn the engine off you can try braking after pumping the vacuum out - it works just fine.
Though towing a Tesla with regerative braking is the best case. You definitely wouldn't want to tow anything that can't brake or steer with a rope.
