It’s the same in most of Europe afaik. You can’t be filmed as a primary subject without consent. For example, I can photograph you in the background of a monument or in nature, without having to ask your consent.
It’s the same for dashcams, you are filming the road primarily not the pedestrian.
Edit: even better, in France (and iirc in Belgium too) I can photograph you as a primary subject without consent, but I cannot reproduce or distribute the picture of you without your consent.
Look up “Droit à l’image” if you want to know more.
Edit2: Hungary seems to have laws like I initially described, so taking pictures of videos in public should be okay as long as more than 1 person is visible on it.
