World's First Entirely EU-Tax-Funded Public Transport Nation
Estonia gets quite significant subsidies, subventions, grants and whatever other aid from EU so they can afford such experiments.
Interestingly, EU officials are also happy because they see the impact as opposed to having money simply disappeared - which is not an exception. Only EU tax payers and donor countries might not be happy because they have to pay for this fun and for their own transportation too - but who asks them :(
