The process of getting a license plate once home was actually a breeze. I used the website of the Dutch Vehicle Authority to make an appointment (for the following day at 2pm) and they gave me a temporary license plate. I simply had to write this on a piece of cardboard and put it where the license plate would go. Called the cheapest insurance company to get temporary insurance, which was no problem, and simply drove the car to get it inspected.
If you buy a car (which is currently unregistered) from a private person that doesn't have those, you just did something that the bureaucracy didn't foresee and at that point, the best course of action is to avoid as much of it as possible.
At this point I have no hope that any of this will getter unless the german state collapses completely.
On top you got a culture of being on time, which is prevalent everywhere, and you wait for stuff very seldomly, and only for a few minutes. Waiting for anything was one of my biggest irks in my home country, the fact that I can make an appointment, be there 5mins early, and get the service, blows my mind.
While some countries provide a non-binding translation for many things, someone could set the precedent in court that the English translation if relied on by enough people is somewhat binding or similar - Result would be two slightly different (mis-)understandings about the law, due process and bureaucracy from official sources. That could be have unforseen consequences.
Just because many people happen to speak English doesn't mean everyone has to.
