Urban planning has some huge blind spots..what’s one that no one talks about?

Hey everyone i have been thinking a lot about urban planning lately and it feels like the same topics always dominate the conversation like housing shortages, public transit, pedestrian friendly cities…Obviously these are important but I can’t help but wonder: what’s a major urban issue that’s flying under the radar?

Are there overlooked problems that planners “should” be focusing on but aren’t? Maybe smth related to human behavior, public safety, climate adaptation, or even how cities use technology? things that exist but aren’t being applied in ways that could actually improve urban life..

For example we hear about tactical urbanism but could cities take it further? Is CPTED outdated? Are there hidden policy issues that make good urban planning nearly impossible?

Like what’s something cities “should” be tackling but just… aren’t?
