Shifting a large city away from having a lot of car infrastructure sounds extraordinarily complex, expensive, and time consuming. I would potentially support it, but surely scooters are cheaper and quicker to implement.
Remove all zoning laws and it takes care of itself over time. Zoning is always "keep [thing people want] away from [place where people want it]".
All that accomplishes is putting services that people want further away from them.
Very much the ideal. Unprotected bike lanes end up as parking for gig workers way too often.
For example, make it fully legal to do whatsoever you want to an unmanned non-emergency vehicle parked blocking a bike lane. Very soon an industry of car-destroyers would pop up producing amusing videos for everyone to watch.
It's like hotfixing a completely broken pile of spaghetti code in prod, it'll save your sunday evening but you're in for 6 months of rewrite anyways
