But honestly, if someone keeps honking behind me while I'm driving, I get startled and end up stopping

‌
One of the accidents I frequently see whenever I watch Han Moon-chul TV
is when the car in front stops because the car behind keeps honking, leading to a rear-end collision.
Looking at the comments,
there are many saying things like, "If you've entered the lane, just go. Why stop just because they're honking?"
Of course, those comments are correct,
but I've found that if you don't have much driving experience—or even if you do—you tend to stop if someone keeps honking behind you.
In reality, there are many cases where people honk specifically to tell you to pull over.
When I was a beginner, if someone honked behind me,
I used to think they had something to say and wanted me to stop, so I'd get startled and pull over.
That's why even now, even if another car makes an aggressive lane change in front of me, I don't honk at them.
I'm afraid they might suddenly stop and cause an accident.
But even now, with more driving experience, I still have this habit of flinching and wanting to stop when the car behind me honks.
Thoughts like "Did I do something wrong?" or "Should I stop and apologize?" immediately pop into my head.
I understand that an angry driver has no choice but to honk,
which is why I think driving is so difficult.
I've been accident-free so far, but I know that's just because I've been lucky and others have been good at avoiding me,
so I always try to drive with humility.
