If the restaurant is the only source of food around, what do you do then? Not eat?

It transpose into the fact that North American societies made car centric cities with poor public transit where many place that aren't a city, you need a car to literally do everything.

And even cities cut budgets for public transit.

A simple example from a friend of mine. He makes an effort to go to work by public transit instead of taking his car.

If he takes his car, it's a 10 minutes ride. If he takes public transit, it takes him an hour to get to work. I wouldn't blame him for taking his car to get to work.
