Never in my life have I had the option to choose between public transportation or driving. While growing up and studying in Mississippi, I had to drive. No one uses the bus system unless there is absolutely no other choice, and I sometimes forget that not everyone has a car (I'm still baffled that some of my European friends still don't know how to drive even though they're in their mid-20s). I heard a lot of people complain about the lack of public transportation, yet I wholeheartedly oppose the idea of bringing a significant public transportation system to Mississippi. The state is simply too rural for a large system to be efficient and cost effective. There are only 3 million people covering an area about the size of England. In Scotland, I had a love/hate relationship with public transportation. With my student discount I could get great deals on bus and train tickets, but otherwise the tickets would be horribly expensive. Taking the train might be more cost effective only if there is a heavy tax on petrol. Yet that would mean that getting from place to place would always be horribly expensive. I noticed that many Europeans don't travel across long distances as much as Americans do. For instance, while working in France my German friend told me that his home was about 6 hours away from where we were working in France, I said, "Oh, so you can drive home for the weekend with no problem." He was shocked, "Of course not. Who would drive that far?"
Before coming to DC, my brother-in-law asked me if I would take my car. I told him of course I would take the car. He thought that DC was a city like New York where everyone just used the subway system. Now that I've been in DC for a while, I've learned that most everyone drives from place to place instead of taking the metro. Those who take the metro regularly are usually college students, government interns, those who work in an office building somewhere between Dupont Circle and Union Station, and those who live within walking distance to a metro station. The metro system is also pretty good for tourists going to monuments and sports fans going to games. Yet the total number of riders is incredibly small considering the size of DC. In 2010, the metro had a daily ridership less than 600k. I'm not sure if 'ridership' means one-way trips or two-way trips, but either way that is a low number considering that the District population is 600k and the metro population is 5.4 million. Depending on how many of those 5.4 million are employed, I've figured that about a third of workers use the metro to get to and from work (I'm assuming 840k use the metro to get to and from work, which is a generous number). One third seems about right after talking to friends and family here. People choose to drive in DC for different reasons. First, the trains can be just as slow and unreliable as traffic. The metro can be especially problematic during rush hour when certain lines, like the Orange, are well beyond capacity. Since multiple lines share the same tracks, they get so crowded that they can't fit any more trains into the system. Then trains have to stop and wait for other trains to get out of the way, but then that causes more congestion. Once, I was on a train that had several more stops, but the HQ told the train to skip those stops and take everyone to the end of the line because the line behind us was too congested. Everyone who wanted to stop somewhere else at a certain time was shit out of luck. Shuttles could take them to their stop, but that takes a lot of time. Second, the metro doesn't go many places. If you don't work in one of DC's major office building districts, the metro makes no sense. There simply aren't enough lines to take people from where they actually live to where they actually work. Third, if you drive to a metro station, by the time you park and walk to the train you could have already driven at least part of the way to work. That's especailly true if the driving commute is 30 minutes or less. At least those are some of the reasons why I'm not a huge fan of the metro system.

Unlike the regular metro map, this map
shows how far the stops are from each other
and where the lines actually go.
There are some advantages to the metro. For instance, I enjoy reading on the metro. Once I get on the metro, I don't have to worry about traffic anymore. Since I get on at Greenbelt at the end of the green line, I usually can find an empty seat. The metro would also be nice if I lived much closer to a stop and had a bike since commuters can take their bikes with them (a lot of people hate the busses, but a bike is a good alternative to the bus). The metro is also good for when there isn't enough parking where I might work.
For a while I thought the biggest advantage to taking the metro was the price, especially with gasoline at $4 per gallon or higher. However, I've begun to notice how all the metro fees add up, especially during rush hour when the price gets jacked up. One night I sat down and did the math to figure out if the metro was really cheaper than driving. I calcualated the cost from my uncle's house in Maryland and from my friend's house in Virginia to a place I've done some temp work in Arlington.
From Maryland Suburb to Arlington
Metro:
Total rush hour metro fare- $10.40
Parking- $4.25
Driving to and from metro station- $6.20
One day's commuting cost- $20.85
Driving:
Driving to and from work- $10.60
Parking- $8.00
One day's commuting cost- $18.60
From Virginia Suburb to Arlington
Metro:
Total rush hour metro fare- $7.70
Parking- $4.50
Driving to and from metro station- $4.00
One day's commuting cost- $16.20
Driving:
Driving to and from work- $7.00
Parking- $8
One day's commuting cost- $15.00
In addition to being slightly slower than driving, I was amazed to find out that taking the metro is slightly more expensive than driving. That's the main reason I'm peeved about the DC metro. Yes, it's much cheaper when it's not rush hour, but I have to be at work at a certain time. There are different factors that could make driving or the metro better. For instance, the company I temped for gives its regular employees a discount on the parking garage. That would make a huge difference. Other employers, especially the federal government inside the District, gives some employees money for their metro fares. One might think that my calculations would be different if the price of gas went higher or if car maintenance was more expensive, but that's not so much the case. I still have to drive back and forth from the metro station, so higher gas prices wouldn't make the metro cheaper.
For the time being, I'll continue to use the metro if I'm commuting from Maryland because I'm not very familiar with how heavy traffic can get on certain roads. The metro is the safer bet for now. However, if I'm in Virginia, I'll probably drive to and from work depending upon where that work is.
