People always think of Japan and their poor salarypeople, sleeping in the train, missing their stop, and have to be waken up later and hope they aren't on the last train. How sad it is that they have to work so late till night to take a late night train home.
What they didn't think of is that they have a train to sleep in. Not putting aside the sometimes brutal work culture in Japan, but a lot of people can sleep on their way to work and back. Not us.
Had a terrible night and lack sleep? Drive to work. Kids throwing a hissy fit and you're exhausted dealing with em? Drive em to school. Had a busy or terrible day at work? Drive back home.
