Loads of north America is just fuckin empty. Canada's population density is around 4 people per km², and 99% of us are crammed up against the 49th parallel(the border) as most of the rest of the country is a frozen wasteland.
When I was living in London, my wife and I decided to rent a car and drive up to Edinburgh for our yearly visit to her friends. Told my coworkers that we were driving and they couldn't believe it.
"ISN'T THAT LIKE A 7 HOUR DRIVE?!"
Motherfucker, back home you do a 7hr drive to go camping on a regular weekend....

It can be pretty neat during the day, but man does it fuck with your senses at night. If youre lucky youll have the full moon and/or the milky way. Also it can be anxiety inducing if you didnt realize how big itd be and youre gas starts getting uncomfortably low.

Empty doesn't necessarily mean untouched. Replace towns bleeding into each other with industrial farms.
