"what does this do if we lose power" is literally the first thing anyone is supposed to think of from a design standpoint when they have an actuator somewhere.

Part of the problem is that "fail fast" which is fine when someone's email doesn't work for 15 minutes turns into "fail deadly" when you're dealing with a physical thing in the real world.

My understanding is there is, in-fact, a mechanical way to go about it. But it's nothing but a design failure it's not evident to an average user. A deadly one.

Canadian engineers have a tradition around an iron ring as kind of "class ring" when you graduate (they've kind of tried to push it in the states but it didn't catch on in the same way). The notion is "it's heavy, but not because of the weight". It's meant to be a reminder as you go out into the world that what you put on paper has real implications.

I get down on Tesla specifically because they've got... I don't know, 100 years of history to learn from? Like you had the whole world on your side and you gave us the effing "explode on rear impact" pinto, but without the luxury of saving the victims the cremation costs.
