I recently just stopped driving into New York City from Westchester. I used to have no qualms about driving for an hour and then taking some 10 minutes to find parking, but there is a better way. The Metro North is 35 minutes to Grand Central and parking is relatively easy, especially when I am going in on an evening. I realized it isn't worth my time to drive in given that I can do other things on the train such as read or write or just close my eyes. As a bonus, I am certainly less stressed when I get where I am going.
