The price various a lot. - In Belgium you can ride from anywhere in the country to anywhere else for 7.5€ (if you buy a prepaid ticket for 10 rides), which is hard to beat even with a car with great mileage. - In Portugal, you can go from Lisbon to Porto for 15€ (buying a couple weeks in advance). By car, that won't even cover the tolls.
