Ban cars in the main street. I'm sure you can learn to walk one block. You might even find you enjoy it when you are not having constant near death experiences with cars.
All those parking spaces are now spaces for pop-up businesses. Food vans, shipping containers that are now selling vegetables, outdoor dining, art fairs, etc.
You can now legally live in those apartments that people used to live in built above the existing shops, before that was made illegal for reasons unknown.
When I wrote the above I thought, hah someone's going to be like 'bUt HoW WilL tHe vAnS gEt tHeRe jEeNiuS?'. But then I thought, nah noones that iamverysmart. Yet, here we are.
So it's not a car ban and that's the point. You'll have to either make an exception, allow electric only traffic or something else. Many businesses also "need" access for disabled and elderly, so taxis also get a pass. Very few models let you reclaim any streets or parking. Cut down a little, maybe. And that's good of course. But just saying "ban cars" is naïve.
