Call me Dad
Then you obviously didn't read a word I said about Europeans having countries that are closer together so they NEED passports more than an American does. Ours is a want. You live in the UK and want to take a short flight to Italy, you need a passport. I know. I lived thereWhat you're saying doesn't hold because majority of Europeans have passports and leave Europe and they have more diversity in landscape than USA.
Let me make it easy.. If I lived in Italy, I'd need a passport anytime I was on a plane longer than 2 and a half hours.. And that's the two longest points. It's 620 miles long. So any travel I do, I would need one early..
In the states.. That's a trip from NYC to North Carolina. In the 1990s people would look at you crazy for flying that. Hell, people still drive to atl and florida instead of flying to save money. Again, you'd drive over 15 countries in europe doing that. So you'd need what?
