Tricky car doors

Are these real? Some of the vids seem to be 7 to 10 years old. Anyone ever seen on in person?

We had at least two threads about these doors before. I think the consensus was that they are real but too impractical for mass production cars

These doors were promoted with that video as you say for years now. As I recall, there was a custom car company that offered to install them on Lincolns for an enormous cost. I don’t see such doors as an advantage. A wind will blow your stuff around. Rain and snow will blow in all over the seats and dash board. Your privacy is compromised. They supposedly solved the safety issues, but now side air bags are common and this might be difficult to design. In the end I believe it is one of the car show type displays that will never see a mass market.
