That's basically getting into having radically different lifestyles and development patterns and you not liking a car-oriented one. (And hey, I agree with you and live somewhere I can walk to most things, including groceries. But that's not the average American lifestyle).

Approximately 92% of US households have at least one car, 59% of US households have more than one car.

The fundamental point that I am making is: Americans do not typically go to convenience stores to buy groceries, it's not even a consideration. The places most do go to buy their groceries do have fresh produce + meat and so on. They tend to just make less frequent trips and buy more at once.

Since they are getting there by car, it's also easier to buy a lot more at once.

When they get home - they also have a much larger refrigerator + freezer (possibly more than one) than is typically seen in Europe to store it in.
