Counter-point: The "everyone needs ridiculous amount of driveway space" rule existed in a suburb I lived in. We had exceptionally wide streets, but parking any car in the street for any amount of time was strictly forbidden. All of my neighbors complained about how "ghetto" our street looked when my parents visited and parked in the street. People really actually hated the idea of anyone parking in the street, even for a weekend, and so we needed driveways that were large enough to handle the 3 days of the year when we had a couple extra cars around.

That rule was dumb and unnecessary, but was also not a "pointless regulation", it was not "regulatory capture" by the Big Driveway Cartel, and it definitely wasn't a response to a legitimate need for more parking (again, super wide streets that sat empty). It was just a reflection of the deeply held convictions of an extraordinarily parochial population.
