Looks like this experiment is conducted in US. If you are walking in US, you'll end up on nextdoor and if you went one way, changed your mind and went the other way, your picture will be on nextdoor from many people's ring/etc cameras, reporting a suspicious person walking on the street and if other neighbors have seen this suspicious person.
