I'm not going to move over for someone who doesn't understand how to merge
That could be dangerous. Why do you insist on not moving over?
It's just amusing when you are in the car next to that person
It's not safe to make judgments about someone else's driving and make things dangerous on the road. You could seriously harm yourself or others.
Next time, I'm going to honk and show everyone that they're terrible drivers.
Just because you don't like someone else's driving, doesn't mean you are allowed to make it difficult and dangerous to others. It's very easy to get hurt in driving, and I believe it's everyone's responsibility to drive safely. Don't you want to go home in one place, just like everyone else?
