The train station car park of a working class suburb is always full on a weekday until maybe 4:30pm where you may get a few spots here and there. But the train station car park of certain wealthy class suburbs are only half full throughout any working week day!
Every time I need to take a train to the city in the late morning or early afternoon, I'll drive from my Zone Two suburb to a Zone One train station in a wealthy class suburb because the Zone Two train station car park in the working suburb that I live in is full as early as 7am (this time is getting earlier by the year)!
And every time I took a train in that Zone One wealthy class suburb, I would be reminded of the Rich Dad Poor Dad book by Robert Kiyosaki. The rich don't work for money. And that's why their train station car parks are never full!
