In one instance, a car's traffic sign recognition system picked up a

 My father has some friends who steadily run into that problem on the
road that they use every day.
 When you say that the system is mandatory in EU, does that mean that we
are not allowed to disable it? I select speed according to my gps, and
that is 5 kph faster than the speedometer reading. It's pretty much been
the same with every car that I rented before I bought one.

Yes, car speedos are allowed to over-read but not under-read. GPS is more accurate (except in tunnels).
It seems you can disable the speed limiter, but you have to do that every time you start the car (and the maker may perhaps bury the option several menus down).
