Why do you need to drive a giant fire truck down the alley? […] “we need to carry water and I don’t know what a fire hydrant is”

Fire hydrants provide water, but you need to run the water through a pump to increase the pressure, and a fire truck acts as that pump. It also allows for the attachment of multiple hoses so that water can be sprayed in multiple locations.

And if all the roads are very narrow, how are you going to get a moving truck or other delivery vehicle in? What about a plumber’s van? What about a small personal vehicle? Two meters isn’t wide enough for any of those, especially not with outdoor seating. Six meters gives space for service vehicles to coexist with pedestrians, cyclists, and seating.

I don’t agree with not having tall buildings either though. If the majority of housing is dense apartments above ground-floor businesses then there’s much more open space left for nature preserves, parks, and gardens. I mean, they don’t need to be skyscrapers, just 3-10 stories maybe. You can also save a lot of space with row houses.
