Wow, that's pretty blinkered of you. Off the top of my head, it would probably be preferable to people with a physical disability, people with a sprained ankle/wrist, people with the flu, people with a hangover, people with two small kids taking a nap, people working from home with a deadline, busy people in general, people who live outside of a reasonable walking distance from a store (can include those who live close but in a difficult to walk neighbourhood), people who need to buy more things than they can easily carry...I'm pretty sure I'm well over 1% of cases already.
