In my experience, every urban street in Australia is full of parked cars. It wasn't like this when I was growing up and we would ride up and down our cul-de-sac or kick a football, but now that same street would have 12-20 cars parked within a one block segment at any given time.

People can afford more cars and would rather make use of the public space for parking than fill their driveway or have to shuffle cars if they're parked behind one another.

I leave my second car parked out front because it's slightly more convenient than using my double driveway (crammed to get kids in the car when two cars are parked there), and because I have a pool table and table tennis table in my double garage. I am a part of the problem!
