The Dutch tram system relies on a person buying a ticket beforehand and then being honest enough to stamp the ticket at a machine located on the tram. If a passenger is caught without a ticket, then he is fined on the spot for about 40 euros. In contrast, in the previous city he worked, New York, there were technical controls to prevent one from cheating. The Dutch are largely voluntarily complying with paying even though they could probably get away with not doing so. People seemed to be acting based on motives other than avoiding punishment or seeking personal gain.”]
