When I woke up this morning, I was feeling virtuous—and also late—and decided to walk to the tube rather than taking the bus, easing the strain on Transport for London’s contractor First. I’d already skipped my morning shower, which made life easier for Thames Water, and will pay off later in the day for British Gas, as my boiler stores the unused hot water rather than heating more. I took the second train from my station, rather than the first, which got me a seat and made life just a bit easier for everyone on the marginally less-crowded carriage I had decided not to squeeze my way into. At the other end of my journey, I darted across the road between a gap in the traffic, which appeared to piss off a taxi driver. I hope he didn’t take it out on his next fare.
A city is complicated. Millions of autonomous individuals make billions of decisions every day, and to even guess one person’s choices perfectly would make you a savant. But at the same time, a city is simple. Every morning, a human tide goes from the outskirts to the centre; and every evening, it makes the return trip. The history of the SimCity series of games is of a slow shift from the latter view to the former.
