A certain mayor has proposed a fee of five dollars per day on private vehicles entering the city, claiming that the fee will alleviate the city's traffic congestion. The mayor reasons that, since the fee will exceed the cost of round-trip bus fare from many nearby points, many people will switch from using their cars to using the bus.

问：Provide the best evidence that the mayor's reasoning is flaw

答案：The cost of parking fees already makes it considerable more expensive for most people to take a private vehicle into the city than to take a bus.

求助答案如何mae the reasoning flaw? 谢谢！！

城市已经采取了收费（parking）但还是没有阻止人们私车入城，现在又采取收费来防止私车入城，这是个flaw，达不到预期效果。
不过这种解答方式是考场是想不到的，还是5排4剩1的排除法来做比较好
