Too large of a splatter to be a milkshake out the nose!
I would concur with the 40mph. Taking a WAG (Wild Assed Guess) from the angle of spewage. Just be glad she got the window down.
My buddies (pregnant) wife yarked too quickly to get the window down. Thought they had it all cleaned up till after a few days parked in the sun. Did I mention it was chocolate milk....
Just hope it nothing CSIish like... head out the window driving too close to a telephone pole...
