A crack has appeared in my windscreen. One day it wasn't there, the next day it was.


It is right up in the top left corner, so it is not a vision obstruction. The odd thing is, if I run my finger over it on the otuside, I feel absolutely nothing - no chip, no raised edge or gap, nothing. I can feel the crack only on the inside. There has definitely not been any impact on the inside of the screen in my ownership, and it wasn't there when I bought the car.
This is a new one on me. Does anyone have any idea how it could have happened? Could it have been a stress point in the inner glass layer which has finally given way after 50K miles? (No, I'm not looking to approach MB for anything; I'd just like to know if it has happened to anyone else).
