You got 6 million trucks registered in the EU alone [1], plus fleets of trucks registered in adjacent states such as Turkey or Serbia, or old trucks out of the new Eastern European states that predate their EU membership and, with it, mandatory governors. And loggers can be manipulated as well, if you do it right there is no chance of finding that out without taking apart the truck.
Not every country is as thorough as Germany is in technical inspections, trucks from outside the EU don't need speed governors, and as long as you don't race your truck in Germany, France or Austria, chances are high no one will be bothered enough to pull your truck over for a detailed inspection on an examination wheel. Or you simply have two datalogger cards, that you swap out when going into one of these countries.
