I agree it's annoying there's no way to toggle the orientation of the chairs though, especially since clicking random 6 times got me 5 videos in the "wrong" direction and only one the right away around.
As an example, UK law: you can legally photograph/video anyone in a public place, without their consent. Limitations to this exist, e.g. if the person feels they're being stalked or harassed, they can complain, and you could be arrested for breach of the peace.
Basically the only exceptions to this come from Article 23 (which is unlikely to apply) and Article 85. Article 85 covers "journalistic purposes or the purpose of academic artistic or literary expression", but it requires separate law in Member State and these then set out the requirements what actually qualifies under it. The standards for that tend to be much stricter than US' First Amendment (which allows essentially anyone to say that they are press).
I have to add, though: if you meant this as a joke, it's actually really funny! So it's a bit of a Shrödinger cat I suppose.
You don't need a simulator I think these are the best walking videos on the internet.
