I think it’s no easy task to reform a city away from being car-centric. In my home town of Ghent (in Belgium), we’ve had several iterations of a traffic plan that gradually reduces the number of parking spaces, rises taxes and car related costs, makes streets one way or deprioritises cars (e.g. a car doesn’t have priority over a bike anymore) etc. It’s not easy but the city today is a lot more liveable than it was when all this started.
But then public transport has to improve also. You cant make owning a car impossible without offering alternatives.
It's a good illustration of why solving climate change isn't just a matter of individual actions. We need to reconsider the whole infrastructure, and you can't do that from the bottom up.
Honest question: What is the hard part? If you took all of that stuff and did it as quickly as you could somewhere else, what's would be the biggest issue? People + resistance to change of any kind?
The outcome seems so obviously good. I have never heard of anyone complaining about a city becoming less car centric, but maybe somehow it's an under-represented story?
The cities were recently reformed to be car-centric(1960s) and can be easily reverted.
All it takes is an understanding how fucked up it is to operate a 2 tonne personal vehicle everywhere you go(if you are able, which most people aren't, legally or mentally), spread the general knowledge and make a long term commitment to public transport, walking and bicycling.
