If I'm in a bad mood, I'm not going to let other drivers over in my lane.
For what reason would you want to stop other drivers?
I don't really. Perhaps I'll just drive on the left side of the road instead instead if they overtake me on the right.
You're allowed to be in a bad mood, but disrupting and being obnoxious while driving can be dangerous. You could cause a serious accident and is that something you want to risk?
Not really, but I'm just going to do it anyways.
Being ignorant and not caring about others is never good, but especially while driving, as it can have horrific consequences. You should be a calm driver and understand that you're sharing the road and need to be careful and allow others to be safe as well.
