Even in suburbs, it does seem that the potential of in-fill development and mixed-use repurposing is undervalued. For example, I've lived in many low-rise apartment complexes; they always had one or two ground-floor units that were unpopular and frequently vacant because of their proximity to a road or something, and it never made any sense to me that they couldn't be converted into a small commercial space for the neighborhood. Something like a small cafe or corner store. With a higher commercial rent, residential rents in the area could be lower, and car trips to similar spaces would be reduced. These complexes also were always roughly 50% parking by land-area. Converting some amount of it to new units would be so helpful. Or even something as simple as converting a one or two reserved parking spaces to one of these (https://i.pinimg.com/736x/56/42/1b/56421b53bcffe6b0c92369c4463c54d4--cycle-shelters-bike-storage.jpg https://i.pinimg.com/736x/56/42/1b/56421b53bcffe6b0c92369c44...) so that cyclists wouldn't have to lug their bicycles up 2 or 3 flights of stairs after every ride. The "logic" of anti-pedestrian thinking is just a desire not to see anything at all change.
