As I mentioned earlier all this is interesting rhetoric and opinion but the fact is people rarely drive in a manner "they" feel is unsafe or uncomfortable. They drive the way they think they should drive and probably have driven that way for years without incident. As long as their driving is legal they will continue.
You and I might complain about the way a person sets up his rig, how much he chooses to overload his TV, the amount of fish tail they ignore and the speed they are traveling at but unless one can prove they are in violation of some law they are perfectly legal and we can only shake our heads.
My opinion of safe driving means nothing to the next person.
As for braking, tow vehicles have brakes, trailers have brakes. Anyone who thinks they can stop their rig as fast as they can stop their tow vehicle alone is in for a rude awakening. :)
Be safe.
