The suburbs used to have a lot of those kinds of places. Car-centric infrastructure is not the problem. People used to go to church, join bowling leagues, spend Sundays in the park, etc.
I blame the internet. There just isn't much demand for couples to leave the house anymore with the world's entertainment at their fingertips. When the rest of society stays home, it becomes more expensive for those young, single people to support public spaces.
That was never the suburbs I grew up in. You had to drive to go anywhere, and it was spectacularly lonely. I've spent my whole adult life avoiding such places.
Long ago, if you had to drive to go anywhere, your house must have been surrounded by oodles of other houses and hence friends existed to hang out with before some friend could drive. Once someone could drive, the friend crew was good to venture elsewhere.
The problem today is the nanny states don't allow a 16-year-old to transport other kids in their car until many hoops are cleared. We collectively decided that such social/transportation kneecapping was riskier than having our kids be lame during their sophomore/junior year of high school in the suburbs.
