It would be my opinion that the window opening was reduced by the cage structure that was rather substantial. To the best of my memory, the panels around the cage, including the roof panel were not deformed to the point that would hinder escape.

Not that it is of any importance or not... Take a look at the crash video's again, if possible on a HD TV so that you can really see the detail of the car. The Windshield was never even damaged and the roof never once touched the ground till the last very very soft roll where the car finally stoped. I would be amaizingly suprised if the cage had any sort of deformity considering:

A: Very well built car
B: The "roof" never took a hit


I am not sure I understand what is wrong with all you people and all the complaining and/or argueing so much about Hans vs. Isaac. They are both great products from what I am aware of. We have witnessed on TVor in real life plenty of reasons why they both have saved lives. If you are a Hans or Isaac wearer then support the overall cause for safety, not the product. One might be safer than the other but that is personal preference. We can all admit that both are safer than nothing.

Work on a bigger cause:

a: Make Head & Neck restraints affordable for the average or lower end club racer.
b: Help the process determine the best "restrictions" on what products actually do function to a specefic level (SFI or other). - Maybe their should be an a test that requires an exit to be made in X number of seconds.
