I was in London last October. I live in Austin TX but was born and raised in Boston. I have also lived in Los Angeles, San Francisco and have traveled some to different cities in the United States.
I can not speak for all of Britain nor for all of North America.
One thing that I seriously loved about London is that museums are free. In the United States, many of the museums cost and are pricey in my opinion. However attractions and sites in London were very expensive to get into.
I loved all the squares and parks in London where you could sit and enjoy and people watch. Everyone that i went in London, there were wonderful places to just sit and people watch and enjoy
There are green spots and squares and parks in the United States but there do not seem to be as many or as convenient. Also in the United States, you might find homeless people sleeping on the benches. There is crime in the parks. You have to watch your surroundings..
Public toilets in the United States are always free but some are not terribly nice and not always easy to find. And they are bathrooms, not toilets.
London has fabulous public transportation. Austin, Tx where I have long lived has mediocre public transportation. Some American cities like San Francisco, Chicago., Boston, etc etc etc have very good public transportation but the stations or buses can be dirty and there is crime. There are homeless and mentally ill people sleeping around the stations. You have to watch out.
There are fast food places everywhere in the United States, for better or worse. If hungry, you can walk in and get something fast but not necessarily healthy although fast food restaurants are improving.
I do not remember seeing many homeless or mentally ill people on the streets of London but in American cities, we have serious problems with the homeless and the mentally ill on the streets.
I had no desire or time to watch the videos.
