I can't figure out how they think these utopian 15 minute cities would work if they don't have a working transit built in. It's so weird

Isn't the assumption that the 15 minute city is a neighbourhood in a functional city? There should be transit.

It's so weird, do they think handicapped people can bike and walk everywhere or don't exist?

I lived in something like a fifteen minute neighbourhood. I saw people in wheelchairs around. They appeared to use the same amenities as everyone else.

Do they think parents love sending their kids down the block to play by themselves instead of the backyard?

Our kids preferred going to playgrounds because the toys and play structures were better. And they ran into kids they knew.

Their choices aren't going to make sense for a ton of people.

I'm not sure what would be bad about a fifteen minute neighbourhood. It's just a normal neighbourhood, with stores, schools, work, and civic infrastructure.

As far as I can tell, a fifteen minute neighbourhood only adds to what exists, rather than taking away.
