Hello! As a student of psychology I will answer your question, I hope it is not too late.
Let's go over this preconceived idea that "Women in general are bad drivers".
Critical thinking is a skill that you develop when involved in situations that will force you to make decisions by analyzing and preventing consecuences. This comes with advantages and disadvantages, which will make you more skeptical to ideas or comments without argumentative facts.
Now, objectivity and curiosity go in the same direction. They will open your mind but at the same time close it in the other direction. this preconceived idea that "Women in general are bad drivers" is the result of previous events and the application of these four attitudes plus human nature and personalities.
Feel free to apply this to any other event or situation in life, for instance, the ugly saying of "Women are made to stay at home while men go to work"
