I'm not sure about the listed facts... I opened up Helsinki where I live, and got this: "Every residential building has a sauna -- it's not a luxury, it's basic infrastructure, like having hot water."

Certainly it's very common, but certainly not "every" residential building has one.

Nice idea … did they consider warping the map, I wonder. Not sure why parks in London rank an E or F on the “daily life” scale

Your 10-minute walk is not my 10-minute walk.

Dublin scores higher that Amsterdam? If it is that wrong in that instance it makes me question is there anything useful in there at all?

Just fyi, Dublin has a rather dense core (too dense) surrounded by a 10km wide ring of extremely low density suburbs where services can't function efficiently. Everyone has to drive a car. It's a Detroit model disaster.

Whereas Amsterdam is a uniform medium density throughout and at its border it just ends and gives way to farmland. It has the right density throughout for services like transport, hospitals, schools, recreation, shops etc. to work.

Coastal areas have a bug where the first line of sea tiles report results > 0.

Why does the site use someone a bicycle for the icon for "Car Infra".
