I actually live about 1/2 mile from a great grocery store but regularly (~once per week) drive 2.5 miles to the greatest grocery store. It's not so bad. It's even easier to go that far or farther for people in the suburbs with fast roads or highways that go to their neighborhood-ish grocery store, rather than my town of Berkeley which has weird traffic calming patterns to try to actively discourage me from driving to the Berkeley Bowl West.
