A major city is the absolute worst place to be in the event of a zombie uprising. The population density alone spells trouble, so the farther you can get away from civilization, the better. At the very first sign of trouble, you need to get right the hell out of there. In fact, everybody does. And what happens when everybody in a city needs to get somewhere at the same time? Like, say, during rush hour? That’s right: deadlock. It’s just that this time, there’s a bit more emphasis on the “dead.”
One man’s traffic jam is another’s buffet line.
Blindly following your knee-jerk flee response has dropped you straight in the middle of Super-Rush-Hour, a hellish place where you sit futilely trapped in a confined space, surrounded by people who may or may not already be infected, but are certainly standing around looking delicious to the zombie hordes. You just wanted to get out as quickly as possible, but now look at you: Stuck in an unmoving meat-line with a thousand other morsels and the only thing your car is doing is keeping the freshness in until the ravenous human can-openers get there.
