The correct answer is A) Not treating bicycles as a vehicle will result in a decrease in traffic tickets given to car drivers.
The statement that shows the flaw in the argument above is "Not treating bicycles as a vehicle will result in a decrease in traffic tickets given to car drivers."
This is not the case because the ticket issue is that the drivers of the cars were used to not strictly followed the transit laws. Once that the Police officers started to enforce the law, the drivers suffered the consequences of not following the law, as in the past. So it is not an issue of the bicycles, but drivers transit education and the strict following of the law for everyone.
