Riddle/puzzle

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.

Yes. (Using the same wires as the demister.)
