I only know what I've seen on TV and things my daughter's friends say and they aren't all that young. We use each other to "fact check" movies and TV shows. I haven't figured out which is worse, the view Hollywood has of Brits or the view BBC/ITV/etc has of Americans. I watch enough brit shows to know they prefer Americans as clichesI think that's mostly younger folks. I've never stayed in a hostel.
The one thing we constantly have to clear up is distances. England is the size of Alabama and Oregon is the size of the UK. The length of time it takes to cross TX just floors them. About once a year, my daughter has to answer a distance question. One of my daughter's friends works on the railway. He doesn't understand why we have so few passenger trains.
