"This invention was introduced at the height of mechanization.  Electronics were still to come - everything was made out of metal and was a true mechanism for the most part.   Swivel seats in their original Chrysler design format were connected to each corresponding door of the car by a cable.  Opening the door actuated the cable.  Actuation of the cable swiveled the seat next to the door outwards, so that the door action and seat action were always connected.   This was a fabulous development until the press was invited to test out some of the new 1960's at a closed course event.   Interior door handles on cars of the time were far less standardized then they are today, and Chryslers had a lever coming out of the arm-rest that you pulled rearwards in order to open the car door while inside.  Most of the bigger Chrysler cars that year also had all power windows, which were still somewhat new at the time in comparison to manual roll-down window cranks that had been around forever.   Story goes that two journalists were in a car and the passenger journalist decided to "roll down his window" (manually) in a car that had electric windows.  The lever that he grabbed to do so was the door handle, and he did it as the car was making a hard left.  Centrifugal force being what it is, acted upon the heavy Chrysler door, whipping the door open, actuating the cable and seat, essentially acting as an ejection seat.   Journalist got tossed out in front of everyone there that day, and Chrysler quickly scrambled to prevent this unintended consequence from happening again!Note here that seat belts were still an option in 1960, and most people didn't habitually wear them.Chrysler quickly struck the cable mechanism from manufacture at the seat supplier's assembly line.  Some early 1960 cars had them installed with seats that were produced early in the production run before the cancellation order came - those cars had the cables laid under the carpet, but left disconnected, and are quite the find for a collector/restorer.  One of the other quirks of swivel seats was that they were marketed in some magazines as a significant improvement for women wearing skirts to exit a vehicle in a "lady-like manner".  The ad that I recall could only have been concocted in the 1950's - so sexist - , but if you're oblivious to sexism as you author such marketing ad copy, the logic is nearly bulletproof!"
