These factors nearly always outweigh the higher financial cost to drive. It is not rational to let such a big, sunk cost sit in your driveway and depreciate. So far, almost no community in the world uses congestion fees, even though it makes transportation extremely fair and helps a great deal to create sustainable travel patterns and livable communities. The problem is that we've spoiled motorists for so long that it is politically suicidal to use such a superb tool. That is very good news for Europe.
Congestion is very helpful, in a huge number of ways, for a city.
And those are the LAST things a city wants. The transit does not seem to be having much affect on the amount of traffic. Again, it is a matter of perception. The transit in Europe takes an enormous number of car trips off their roads. It is rational to use transit in Europe, in other words.
