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'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.
