I used to do this when I lived in New York state and would occasionally travel down to New York city. It was stupidly cheaper to drive (and faster - which WTF whhhhhy). So I would rent a cheap spot in a garage near the outskirts of the city for the day and use public transport for the rest of the day. I remember being mad that it was cheaper and faster to drive and pay to store my car then it would have been to take the train. That's a problem. Especially when I had a train station in biking distance to my apartment at the time.
