I know they were building that in the early 60s because that's where I grew up and where I live today. Well, I grew up in a 1930 house in a suburb, but same zoning.

Also I know there were awful exurbs built during the peak of the bubble, say a decade ago. Sometime between 1960 and "now" suburb designs went badly downhill.

I have observed over my life that suburb street layout corresponds with this zoning trend. If you live in a subdivision/burb with straight lines and many connections to the arterial road, you probably have a grocery store, dentist, bars, and restaurants within short walking distance, but if you live in "bowl of spaghetti" subdivision/burb with exactly one connection to exactly one arterial road, then you probably need to drive at least five miles to buy a gallon of milk.

I think there's potential for all of that to come into the suburbs since it will eventually be so cheap to live there. Artists and squatters can turn these abandon office parks into co-ops and urban farms :)
