Well, of course you don't know very much about cars. You're a girl.
I can't care about cars because I am a woman?
It's true, it's a fact.
It sounds like you're making an over-generalization about what women know based on stereotypes. You should do some research about female mechanics, engineers, or scientists so it's easier for you to see what women can learn anything that men can.
It's not the same. No offense but I don't think anything that a girl says in this conversation is going to be relevant.
That is so wild to me that you think that women can't know about cars! We know our way around a car more than you think, let me show you.
