If only car doors were made this way

Intresting Door - The most amazing videos are a click away

Ever parked your car and realise that you are so close to the car beside you that you can't even open your door fully?

I think this innovation might just help. But I wonder if there is a side crash, would this door hold up? And I notice that the window had to be wound down first before the car door could collapse like that. I am just concerned if the mechanics that move this thing actually gets stuck and you won't have a proper door closed when you drive.
