One of the best things about travelling to a new country is getting to try their public transportation system. Aside from some of the major cities (like New York), America is very lacking in public transportation. In most parts of the country, it is the norm to own a car and use that as the main method of travel. As someone who hates to drive, the train systems in places like Japan and Europe are incredibly valuable. You can quite easily get all around the city without owning a car. In fact, I would hesitate to even try driving a car in some of the major cities. France has such narrow roads with cars parked on either side and an unusual use of stoplights that I would likely cause a wreck in my first day driving. Tokyo gets so busy I would waste the day just trying to get to where I wanted to go. Using trains gets even better if you have a train pass, because then it feels like your own little taxi service. All you have to do is find a station (never difficult), locate the right train, and swipe your magic card to get anywhere in the city.
