Interesting! Most people in the US just make videos about their lives or area, but I do not think I have actually seen videos on the culture except historically.
It depends in what state you are in... America is so diverse I would say that it is hard to cover. Though there are general traits that can be attributed to Americans specifically that others do not recognize in their country. It would be helpful to cover social customs for foreigners coming to the US.
I listen to opinions from people living in other countries and can only wonder how America looks to the world. But it is hard to truly understand growing up here, thinking what we do is normal when it could be different elsewhere.
