So, what would the outward pressure be at 135mph? Not trying to jinx myself, but just saying I have set the cruise at that speed on the autobahn. I think one of the people in another thread had mentioned something about manufacturing defects that occur in the glass that can cause this type of occurance, and that it even happens in buildings at times.
