It does help if you add that as a design requirement, perhaps a five sided box. It's not like it's particularly easy to get out of a packed window seat today.
As long as my flight is still safer than the drive to the airport I'm not going to automatically reject ideas that could be unsafe in very rare circumstances.
Unfortunately the vast majority of the people will probably disagree with you. Mostly because people don't understand statistics well. They will always be more frightened by a few hundred people burnt alive when a plane catches fire every ten years or less than by the amount of people killed in road accidents every days.
