Nationwide License Plate Numbers

This is just my personal opinion, but I still don't understand why they switched to nationwide license plate numbers.
They claim it's to eliminate regional discrimination, but what kind of nonsense is that?
When I see a car with a license plate from another region driving clumsily in my area, I'm understanding about it.
I show consideration because they are from out of town and might not know the roads well.
Of course, there are many people who aren't understanding, but they are in the minority.
They have eliminated all that immense mutual understanding and consideration by implementing a single nationwide number system.
Regional discrimination?? What regional discrimination??
Is it shameful to have a Chungnam number?
Is it shameful to have a Gwangju number?
Is it shameful to have a Daegu number?
