Yes! And the deleterious effect of this is underappreciated and understated. It's not just a convenience and logistical issue; it materially alters the nature and quality of the connection one has with surrounding society, and leads to _different kind_ of social relations over time.
Kids cannot "be kids" when their life lacks social spontaneity (and in fact, there is some question about adults being adults as well), when their life is a directed graph and a collection of automobile vectors, subordinated to the rhythms and whims of their parents to drive them.
As a child, I did not immediately understand this paradigm shift as I underwent it, which led me for years to struggle with this great, nonarticulated malaise for which I had no name. It's only with the benefit of hindsight that I understand that I was unable to cope with living "nowhere in particular", which suitably describes 90% of inhabited areas in the US, including places that are notionally urban. Much of DFW should be reclassified as a rural area.
Maybe you just don't like affluent, segregated suburbs?
The suburbs in the Rust Belt, in places like South Bend, IN (where I spent my elementary school years), or Buffalo, NY, are a lot more dense and palatable in this regard. I'd still dislike living there, but it's a far cry from living truly, honest-to-god in the middle of nowhere in places like ATL, DFW, PHX...
On a separate note, ATL, DFW, and PHX are all awful to me as well, but that's because of the life-draining sprawl, not because they're sparse. I fear for the future of housing every time I have a window seat in or out of ATL looking at those developments.
Yet despite this, I'd say that the decline in the number of kids and young people driving is a fair bit less than it seemingly is in the states.
