I'm going to call a driver a slut
Did the driver do something that makes you want to call them a bad word?
Yeah, he was driving like a slut
What does that even mean? Maybe you should reevaluate what you're trying to express and find another way to voice your frustrations with other drivers.
Oh don't worry, I need to call lousy drivers bad names. I will continue to call them sluts.
Using gender slurs against bad drivers is wrong and doesn't make any sense. It would benefit you to consider the times you've erred while driving  and realize that most "bad drivers" are actually human beings who made a mistake -- rather than willfully reckless lunatics unconcerned about driving safety.
