Warsaw made public transportation free for school-age kids (must show valid school id if prompted) about two years ago, which I think was a great move. It's not really about the cost: this move makes it easier (in many ways) to use public transportation to get your kid to school. It means you don't have to think or worry about your child's tickets, buying or validating them. You just hop on and ride, only remembering about your fare (presumably you already have a way of paying, I use my phone to pay).
