Like I said, we need to adjust zoning laws so that we can have businesses in those areas so that people don’t need a car in order to access a grocery store. As for putting together a step by step plan, I’m not a city planner, just like you’re presumably not actually working on developing self driving cars. Also like I said, people would still own cars even with walkable communities and would have less traffic to deal with bc fewer drivers on the road. I’m not trying to take away your car

Where I live isn’t a fully walkable 15 minute community but it’s still pretty damn convenient. Within a 20-30 min walk to me we got a grocery store, library, post office, liquor store and breweries, auto shop, and a few small apartment buildings. Other than that it’s mostly just houses. Lots of people have cars but still have access to most daily essentials (aside from their actual place of work) within walking distance. Lots of people in the USA don’t even have a grocery store within a 30 min driving distance, let alone walking distance. That’s the sort of thing that walkable communities aim to fix
