They might not be illegal here in Germany, but dash cam videos are regularly thrown out as evidence by courts. (And that's quite surprising, the bar is very high for that to happen in Germany. No fruit of the poisonous tree here.)

Sure, so what? They're still mass surveillance even when their footage is not distributed, or used in court. That's my whole point - surveillance that is kept secret is the real problem, and anyone with a few $k or less will be able to set up a vast surveillance database in a few years - very little of which is covered by laws today (yes, some countries require you to register yourself with the privacy watchdog if you hold records of people, but how would anyone check? They're mostly toothless today already, in many places)
