The analogy is a bit shaky IMO, as you can certify individual, heavily modified, foreign or even self-built cars in EU member states.
For cars, the local certification authority themselves decides what is road-worthy or not, not VW et al. You can add third party parts without the manufacturers consent. This is not the case for Android or iOS attestation, you're pretty much at the mercy of the foreign manufacturer and their local laws.
You cannot prove the absence of e.g. a Veracrypt hidden volume or similar, though. Even if you honestly give up your key, you could still be either
A) held in contempt of court, if the authorities do not find what they expect for some reason and accuse you of using such techniques or
B) if you specify that such behaviour by law enforcement is overreach, have a clean way out for criminals, codified in law, heavily damaging the impact you may expect of such a law.
In comparison: The average rent in Augsburg for a 60m³ flat is around 756 Euros (way more for new contracts and furnished flats), the median net income in Germany is ~ 2244 Euros.
One downside, if you're on the taller side, is that the doors in the Fuggerei are only like 5'8, though - and if you're taller than 6'4 or so, even the ceiling height becomes a problem. :D
Impressive! How many credits did a "normal" class (like linear algebra or calculus I) have? Or how many classes did he have to take to get 40 credits in one semester?
The exam taking phase must have been hell :P
The best I once did was only 48 credits (with the baseline for full-time study being 30 per semester, "normal" class giving 6 credits, european university so only a 3 year bachelors degree) and I was very tired after that semester :D
