In most places I've lived for the past 40 years, I could just walk to the store. I have now four to choose from, all within 10 minutes of walking, and the city center is about an hour away. Ther are also bicycles.

By having groceries, you can make food yourself, at home. You can do this many times, for each time you actually have to get groceries.

As for eating at a restaurant, collective transport ranges from obvious to absolutely necessary, depending on the population density. When my family go out to eat, it's a lot more convenient to hop on a bus or tram to the city center. It takes half the time, if you consider parking, it's cheaper, and you can have a drink or two as well. You also get to engage with each other, during transit.

In the less car-retarded world, food delivery is also easier to do with non-car methods.

In any case, and because I know the kind of responses people reply with... Please don't. I just gave you some examples and a different perspective. Americans are culturally dumb as shit when it comes to considering the obviously better alternatives, in so many different aspects, and I don't really care all that much.
