At least in Spain* it does not work like that, there are very stringent limitations on what you can record on the street, e.g. through dashcams or tesla sentinel mode:

For example, you can't use dashcam recordings of an accident in trial.

* And I don't want to spend a bunch of time reading law but quite sure this is very tied in with GDPR, so I'd say that most probably in all Europe everything you record on the street is still subject to the privacy rights of whomever you record.
