I commuted from Fredericksburg to Reston for a little while last year. VRE->Alexandria(Blue)->Rosslyn(Transfer)->West Falls Church(Orange)->my bus. Minimum 2.5 hours each way. I had to do it for a week until I could afford new tires for my car, and driving cut my commute in half. I couldn't have kept up that commute, and I only had to do it for a month before I could afford to move back to DC. The worst part about mass transit are the time restrictions. If you miss the narrow time slot for your route (assuming it isn't used heavily enough to warrant 24-hour service), you're screwed and have to take a cab, which I'd say runs about $40 per $5 of mass transit.
