In the US, commercial trailers are used like these crappy sheds, you go get one and the ABS unit is gone, the only thing worth stealing. For any company where this doesn’t hold it’s a big deal. The bigger deal is really RV trailers. You power assist, with simple motors controlled by pulling, and you can pull a huge one with ANY car, you don’t need truck, just modified mirrors. Plus the RV trailer benefits from slow s…
In practice it's of course not so simple. Every truck that passes you (or that you pass) will suck you right in if your tow vehicle isn't heavy enough or you don't have good enough grip. Also, (RV/drum) trailer brakes suck so hard that you really want a vehicle with some additional stopping power other than regular brakes (heavy duty transmission, big engine, and diesel exhaust or compression brake). E-brakes work we…
But I think it’s surmountable. Someone in this thread joked you could put the steering wheel in the RV, which is of course done, so really it’s just a question of RV motion not compatible with car. I could imagine problems with this, if the stopping distance of the RV is higher as it is in loaded semis, you need a feedback mechanism to the car not destroy the brakes of the car, same with pulling. Really the advantages are too high, solar charging, weeks of battery, ability to slow move with no car, but no restraints of being a motor vehicle.
