When I get off the train in the evening, I have a choice. I can walk right down the steps (outside) and be in the parking lot. Or, I can go through the doors into the building, across the building, and out the other side. It's warmer, it's quiet, there's a restroom and a vending machine.
But you know what else? When I emerge at the other side of the building, after stopping at the facilities and/or grabbing a pre-dinner snack, the parking lot is a much different place. The mad scramble to get home has no mad scrambled itself a few hundred yards away, trying to get onto the highway. I can now walk across the parking lot without getting killed by oncoming cars. I can walk in a straighter diagonal to my car, because enough cars are gone that I don't have to walk around them anymore. I take my time getting situated (hat and gloves off, heater on, iPod switched from headphones to FM Transmitter), and I can leisurely pull out and get right out.
Try it sometime. It's a relaxing way to end your day.
Now if I could just quit stopping at the vending machine......
