I think the reason parking requirements and mandatory free parking are
getting more attention now is because more and more people are understanding that this rather simple policy choice is what has led to pedestrian-friendly development being illegal in most of the country. It doesn't just make driving cheaper in the way that free roads do, it also restricts any other kind of development. I object to the absurd amounts of money we spend on buildings highways, but by themselves they don't actually prevent non-car-dependent development.
