I lived on a college campus for two years without a car, with on-campus amenities and a very walkable town right next to it. Now that I live elsewhere with a car, I can't see myself ever going to a pedestrian-only area. I just do not like having to walk everywhere. The closest on-campus food was a five minute or so walk away from my dorm room, which doesn't sound like a lot, but I didn't like having to walk even that distance. Classes could sometimes be a 10 minute walk apart. Town was only 10 minutes away but I never went there because I didn't want to do the walk. So, I largely didn't go around much. Not to mention how uncomfortable it could be outside during the coldest parts of the winter or hottest parts of summer. I'd settle for a freezer burned hot pocket instead of having to walk in the biting cold even with a good jacket and gloves.

Nowadays, with a car, I don't mind driving for 10 minutes somewhere - it's actually often enjoyable, whereas walking for ten minutes out of necessity feels like an annoyance and a burden. I don't mind walking when I want to, like on hikes, but I certainly don't miss it being a necessity. There is a fast food place about 1.5 miles from me, which many consider walking distance, but I always take the car there and use the drive-thru even though the way there is very walkable.

The place I'm at right now is a nice compromise of usability for pedestrians and motorists, but I personally plan to someday live in a more rural area and maybe have a small farm, and I'm not bothered at all by the fact that such a place is essentially car-only.
