Riddle/puzzle

[armb]

There is some writing on the back of my car. It isn't symmetrical. A passing pedestrian looks at it and it reads normally. A passing driver looks at it in their mirror and sees the single reflected writing reversed. I look at it in my mirror, and the singly reflected writing reads normally. Why?

It is written on your rear window.

The pedestrian reads it directly
The motorist read it reversed once
You read it reversed twice and so back to the right way around.

It's a transfer on your rear window. You see the reversed writing when you look at it, since you're inside the car, so a reflection will be unreversed. Anyone looking straigt at it from outside sees it the right way round, or mirror reversed if they're seeing it in a mirror.

Very chuffed I actually got this before reading the answer...

Gosh, you folks are so smart!

Why does the motorist see the writing reversed left-to-right and not top-to-bottom?
