Such an interesting perspective, thanks for your contribution! I guess our ‘shopping centres’ are essentially the first condition you’ve described that also have grocery stores attached, and it’s likely the grocery store (in Australia this basically means one of 3-4 companies) that are keeping these structures going in the modern age. Our shopping centres tend to be built ‘up’ rather than ‘out’, with 3-5 storey shopping centres (with up to 7 storey parking lots) being fairly common within city limits that are closely accessible to more than 50% of the population.
That being said though, I live fairly equidistant between two of the largest shopping centres in Sydney and still choose to go to my local, smaller, single-storey shopping centre which is very small by Australian standards (<40 stores) which feels much more like a ‘mall’.
Do you guys have a lot of standalone grocery stores that you can drive right up to, park, shop and leave? Because that’s definitely the minority here!
We were taught a similar trick in physics - point your right-hand thumb in the direction that current (or electrons, same same) is travelling and the curling of your fingers shows the direction of the resultant magnetic field that the current creates.
