There appears to be a big fundamental problem with this design in that the trailer is not articulated. While this will indeed make it easier to reverse, in some circumstances it is potentially very dangerous as whenever you turn a corner the rear of the trailer will swing out into the adjacent lane or footpath.

I'm pretty sure that this wouldn't actually even be considered a trailer under EU regulations and in any case they are required to be connected to the towing bracket using an approved ball hitch.

There is also the issue that this arrangement effectively couples the mass of the trailer to the rear of the car in the yaw plane which is going to have a very significant effect on its handling.
