I live in Bonn and I can tell you that the price is 110% the reason why I'm using my car inside the city. Small calculation: I take my wife to have dinner in the city center on Saturday evening. The city center is 3km from where I live. If I take the tram, that's 2.8EUR for each of us, one way, so 11.4EUR just for transportation. Whilst, taking the car will cost me less than a liter of gas (1.3EUR) and the parking will be 2 or 3EUR. Plus, I feel that the quality of the public transport services really does not reflect in the huge price: constantly being late or not coming at all, poor communication, dirty trams or buses.
