      And thus should require backup batteries isolated from the main power bus of the vehicle, which would be so cost prohibitive the entire idea is made redundant.

        Uhhh…no? There’s plenty of stuff that fails open with no battery backup. It’s called fail safe. When power fails and the door remains locked is called fail secure.

          The problem is that if it was fail open, any Tesla left standing around long enough for the battery to drain would unlock.

          The door needs to be mechanical. Everyone else is mechanical with a sensor to auto lower the window on frameless car door windows.

          Tesla did the cost analysis and decided the lawsuits from a few deaths were less than the profit to be made by not making safe doors.

            Ah! I kept wondering how the fuck opening the door can damage the window. The doors don’t have window frames. That has always been a shitty design.

            I think it’s much worse than that - I think it’s just because they (well, Musk) thought it would be “cool” to have everything automatic and just ignored or pushed aside any safety arguments.

              Not defending the decision. I think it’s bad design.

              That said, supposedly the reason is that the doorframes do not run along the top of the window, allegedly to reduce the weight of the car. Because of this, the window itself has to form the seal, which could potentially damage the window if the door is mechanically opened. The electronic button lowers the window as it opens the door in order to reduce the risk.

              Again, I don’t support this reasoning. I’m just sharing it.

                Ahh - yeah I think you’re right. I remember somebody complaining about damaging their car when they had to open it manually. What a bad design.

          It exists but anything that passively draws power would not normally be preferred for automotive. However with EVs it might not be such a big deal due to the enormous battery.
