So Prague has much cheaper public transportation with gaps in enforcing everyone to pay. There have even been big groups of people who form in order to ride illegally and chip in when a member gets fined – according to them it is cheaper than everyone having to buy a pass. In Amsterdam, there is no possibility of doing this and the system tracks how long you are traveling for and which routes you take. This information can be very useful for innovating public transportation to make it more convenient and altered to travelers needs.
