And they made a couple of bad assumptions in that episode. The reasoning behind placing the sandbag on the glass window to simulate water pressure greater on the outside than the inside had a big flaw in it. The coefficient of static friction between wet burlap on glass is much higher than water on glass. Moreover the sand bag was much smaller than the surface area of the window, thereby placing the same force on a smaller area creating an even higher level of static friction.
The fact is that in fresh water, electric car windows in undamaged doors DO open.
Being a liquid, liquid water exhibits no "coefficient of static friction."
And the "skin friction" between a glass window and water would be very small, indeed.

But still, it looks like we all agree that you should be able to use the power switch to open the windows, and do so right away.
Plan B is to have that safety tool that cuts seat belts and breaks open windows (that WAS a valid test underwater).
I think collectively we have helped our FRiend out pretty well here...
