I didn't get any sound with the video. I did read the little blurb under the picture window.
Yes, I know that glass won't bend (unless heated). That's part of the credibility problem I have with this. Metal will "bend" if made in sections, like a garage door or a fire shutter, but that door is "wrinkle free".
But the problem of supporting the driver and front passenger remains. Let's assume there is an operable door on each side of the car. (I suppose it's possible that they tell you you only get one, but...) With that assumption, the entire floor below the front seat is a compartment, a void, for receiving the opened door. How do you put weight on air and expect an equal and opposite reaction? To span that void from front to rear would take a "beam" of considerable depth, perhaps at least as deep as the void is tall, and you'd need more than one for the entire seat, so just one down the middle doesn't cut it.
I'll believe it when I see it - in person. I don't believe the video.
