Can confirm it is a 20 minute city with your own car/motorbike/bicycle-enthusiasm (year round in 35 degree heat or -7 degree cold). The arterial roads are good and the bicycle pathways are pretty good in any area established before self government.
The new suburbs suck, and if you need public transport it is a tram line that services a single area and buses everywhere else. Live in a new suburb and have to rely on public transport? Sucks to be you...
Pretty good if you have a car/motorbike/bicycle-enthusiasm though. s/ Just choose not to be disabled or too old to drive.../s
Some commutes are more like 30 minutes (by car) or 40 at a bad time. But this is where someone has chosen to live at the opposite end of the city to their workplace, which is largely unnecessary.
I myself walk to and from work (when not WFH) and it takes around 20 minutes.
The guy has been dead for nearly one hundred years and the city still hasn't assigned a replacement urban planner...
My work is ~13 minutes away. There is a Primary and Secondary School within 5 and 20 minutes walk. A supermarket is a 10 minute bike ride away. A hospital is 10 minutes drive away. A top 50 ranked University is 25 minutes drive away.
There is a good question from w-j-w that has been deleted here. Yes - it's a 15 minute car city at 8:30 AM. My commute goes to about 14 minutes...
This is on the days when I'm not WFH - which should also be factored in.
