How Close is this to reality?

Depends if you live in utah or not the cities here function mostly on a grid system

Well you could consider the American one to be a little more efficient since there are less curves/shorter driving distances, but the European one is probably more scenic.

Pretty accurate for my European town. Except our river has TWO syllables, ha ha! We're not a living cliché!

I live in a beautiful city in America that is laid out nothing like this but ok

There is absolutely no way that McMansions would be that close to a Cheesy Roadside Attraction
