A blurry snapshot of the future.
You're missing the way the predictive nature of this. Can't you see the censors over every car space? How they monitor how much of the parking lot is free and how much of it is taken? How the board that tells you how many there are, per level even, and how all of this is symbolic--
Symbolic for how our lives are being neatly shuffled into slots, how we're being monitored, how this represents the very future of our world?
It's a fucking parking lot.
