Sounds like a terrible idea to me, honestly. Even Boeing aircraft still have a mechanical linkage. And Cybertruck won’t be a fighter jet no matter how much Elon proclaims it so, it’s just worlds away in terms of maintenance and safety engineering compared to what happens on an aircraft. Not saying it will be common but some sucker will eventually be killed by this.

  When i hear fly-by-wire i think of wire rope going from the flaps the cockpit

  I think aeroplanes are not a good point of comparison. For one, mechanical steering is still very complicated, with many meters (miles?) of hydraulic hoses, actuators, pressure control systems etc. Two, aerospace is healthily paranoid about QA and failure modes. I'm sure a steer-by-wirw can be extremely safe when done with that mindset. But Im not sure if that's the car industry's mindset, let alone Tesla's. Finally, fly-by-wire offers enormous safety benefits in aeroplanes, because of what it enables. But I have no idea what steer by wire enables for a car.

    This answer seems to generate its own proof. >For one, mechanical steering is still very complicated Yes, and digital steering is by nature even more complicated. >aerospace is healthily paranoid about QA and failure modes. I'm sure a steer-by-wirw [sic] can be extremely safe when done with that mindset What? So if we have the right 'mindset' then we can ignore any complexity and adapt anything we want. Why even let users drive cars now? Make their fleet 100% autonomous. Just do it with a mindset of QA and safety!

> Not saying it will be common but some sucker will eventually be killed by this. People are killed by vehicles every day, and some of those are vehicle failures as well. Saying someone will be killed by it isn't interesting. The question instead is will it fail more often than existing designs, which is something only time will tell. But we've had throttle by wire for a long, long time now, and unintended acceleration issues caused by the system failing are largely unheard of. It's completely possible to engineer a robust electrical system just as it's completely possible to have design faults in the mechanical systems that cause premature wear & failure.
