Thanks for the link, I never had a look at that before. If I look at my car, the variable costs per km (without the fuel) are €0,15 per km. The fixed costs are only interesting if you don't have a car and are looking at getting one, I have to pay those costs regardless of whether I leave it at home or not. That means that taking the car in my example above would add another €18 which does change things a little bit.

However, my main point was that people would flock to public transport if they were using the prices you sometimes see in other countries. For example, in Italy it costs me around €10 to get a return ticket from Florence to Pisa. The trains are slightly less fancy of course but they're still very serviceable. If they could make it so you pay maybe €30 for a return ticket from Eindhoven to Amsterdam, it would make it a lot more enticing to take the train.
