The reason why bus seats are always covered in hideous patterns

It's pretty well known that bus and train seats are always made with HIDEOUS patterns. But it turns out there is a reason for it...

The reason is to hide how dirty they are.

Yes, that pattern is there to distract our eyes from the dirt, grime, and muck that is on/in the seat.

It's not really a surprise considering how many people use them every day but it's still pretty gross!
