I would wish for a public swimming pool / public indoor swimming pool closer by, but I have everything else mentioned in this thread already in my neighborhood, so that’s the one thing I have not in reach of 15 minutes, but need 45 minutes with public transport and as long by car (which I don’t have).

I prefer a bus over this. I can get on the bus in front of my house, leave it somewhere, go shopping/to work and enter the bus at the end of my shopping tour, while with this, I would still have to walk back to where my thingy is, carrying what I have bought and thingy would take space up while parking in the city, while the bus is constantly moving. If we talk about the 15 Minute City (which I already life in, with a bus every 5-10 Minutes) , something like this is overkill for most people and too small/not suited for professional delivery. Currently I pay 49 Euro/month for the bus and other public transport and this is 6.000 - 10.000 Euros.
