Umm… that could have just been the other driver asking the person for their footage from the camera they saw.

Not everything is a conspiracy dude, that’s commonly done after any incident lmfao.

I have cameras and plenty of people have asked me for random footage for thefts and collisions, none being a company or insurance, always the person affected…

Edit, sorry I guess once the police did, but still there’s nothing odd or weird about what happened to you.
