In principle, the small trailer with a small car plan is great. It doesn't really work in the U.S. though. There is some combination of towing practices and regulations that make this not work here.
In the past few decades, we've seen many cars here go from having some decent tow rating to a very low tow rating or saying in the manual not to tow.
Just for example, the Mazda 3 in Australia has a tow rating of 1200kg. In the UK it's 1500kg. In the U.S., towing is not allowed at all per the owner's manual.
I'm not sure what all the reasons for this discrepancy is. I know when I lived in Germany where towing fairly big things with fairly small cars was more common, I noticed some differences in towing practices:
1. They use a different style of hitch that flips down under the bumper instead of the receiver style hitch in the U.S. The German style hitch kept the ball closer to the bumper, which improves stability.
2. The trailer is loaded with a fairly balanced weight distribution so that there is not much weight on the tongue of the trailer. This keeps the rear suspension of the car from being compressed and keeps weight on the front wheels of the car. It has the downside of making the trailer less stable at higher speeds.
3. Presumably because of this lower stability, many trailer/car/driver combinations are limited to 80kph. Car/trailer combinations tend to have a critical speed where they become unstable if the weight from the trailer is not loaded in the front, and 80kph is a typical speed where this can start to happen.
4. Germany requires extra licensing to tow a trailer. Someone who actually gets some training and has to pass a test is going to be a lot safer towing than someone who got 5 minutes of instruction at U-Haul.
