The neighborhood I grew up in was like that. I didn’t notice until I moved away for college and then came back home to visit. It was a 100% residential neighborhood, with no businesses really in walking distance. Anyone out walking was wearing Walking Clothes^TM^.
If someone old enough to drive were just walking down the street as if it was their mode of transportation, not an exercise activity, they would at minimum be stared at with suspicion until they were safely away from the starer’s house and at maximum have the police called “just to check out the situation.”
It didn’t occur to me that this was strange until I moved away to a mixed use neighborhood with businesses and residences and lots of people walking to get where they were going.
