To be fair, typically in America (outside of major cities and certain planned neighborhoods), 4 minutes away implies by car. Even if driving only 20mph (unlikely), the pizza shop would be a minimum 1.3 miles away, which would be more like a 30+ minute walk for a pizza.

On top of that, there's almost no safe walking paths by design. You would likely have to traverse major roads with no sidewalks, crosswalks, or even pedestrian stop lights.

It's an unfortunate design that many are stuck with.

Unironically, yes.

It doesn't occur to most Americans to walk a bit instead of drive.

This is exacerbated by the design of American neighborhoods that discourages walking and encourages driving, which of course becomes a feedback loop where Americans don't walk because their neighborhoods aren't designed for it - or worse - designed against it, and so our neighborhoods are designed for people who don't walk, etc.

4 minutes is 2 miles.

It was cheaper and faster to doordash a restaurant quite literally across the street in college, I tested it a few times when my friends would go to buy food there and mine would come like 10 minutes before they got back. Literally across the street, like a 1 minute walk max.
