That's because American suburbs are culture and commerce deserts, designed to sell cars (and to promote racism! but that's not the current topic). If you own a house in a livable neighborhood, with stores down the street, it isn't that weird for people to hang out in any particular spot. There are perfectly non-nefarious things/people they could be waiting for.
This is what I meant in the second half of my previous comment.
