I spent 2 weeks in England this summer and was so culture shocked at how the cities work. Everything is walkable or you can take the bus, subway, or train. We don't hardly have that here. And even if we did, everything is so spread out.
I live in the 5th largest city in the U.S., about 5 million people in my area. I cant hardly walk anywhere except a fast food place and I live in the middle of the city. I have to drive pretty much everywhere. In England, people would buy a couple things from the market everyday for groceries little by little and carry their bags. In the U.S. we shop for a week or so and fill the trunk of the car with groceries.
