Whenever you start to feel comfortable and hubris starts to set in, make sure you have a contingency plan or a viable, easily-accessible escape route for when things inevitably go tits up. Knowledge of the map is key to finding a way out, so if you’re in a point of interest, chances are there’s a car you can steal with enough gas to make a quick getaway. Other landmarks tend to be labyrinthine enough to lose your adversary if you move fast enough. Failing that, you can always build a tower and use that to escape instead.
