Is it legal from the car or streaming live from his motorbike (Youtuber Moji)?

I found a streamer / youtuber (Moji) the other day, who is also watching Twitch live on his bike. And I just wondered if that's legal, because of license plates, faces, etc.

If he just films himself maybe already. If he does not film others!

Even then, it is allowed, after their agreement logically.

@ Stefan Fanum So yes he films others and, accordingly, their characteristics.

@ Comp4ny True, but do not think that happens.
