With very few exceptions, public transit in America sucks. In the cases where public transit is run by a private company (usually contracted out by the local government), it is much better. I for one welcome private involvement.
Thirty years ago my small hometown had bus service to the closest big cities. Three private companies supplied round trips from one downtown to another several times a day.
Now there is only a shuttle, which costs twice as much, runs only three times daily, and doesn't go anywhere but the airport. If you are car-free in this town, whether by choice, poverty, or disability, you're going nowhere unless you have friends to drive you. So I was excited about what Uber or Lyft could do for the rural car-free...until I remembered how the private bus companies left us high and dry. What's to keep Uber from doing the same?
