    Is there any actual benefit to this approach, or is it change for the sake of change? I can see that it’s probably cheaper to produce, but that’s not a benefit to the consumer. It’s not like they’ll pass those savings along. There’s obviously huge risks associated with it failing, since you no longer have a mechanical link to the wheels of the car.

      Benefits: It reduces the amount of metal (weight) by removing the steering column. The position of the steering wheel can be adjusted more with the lack of physical connection. Up, down, forward, backward. Cheaper due to less metal while simplifying metal fabrication.

      Drawbacks: Electric means inherited delay for less responsive input at this time. Electrical point of failure means if the system dies, can’t turn. Loss of feedback from the surface in the steering input.

    Dunno. Car doesn’t running (resistance from the tires). Moving from one extreme position to another.

    I’m not defending Tesla. I just need a comparison to a “normal” car.

      Lag shouldn’t be an issue for a “normal” car because you still have a physical connection between the steering and the wheel. Worst case you’ll have more resistance if the power steering system fails.

        Exactly, from the driver’s perspective, you know what the tires are doing.

        That’s not likely to be the case much longer, at least in some brands. Toyota got approval to mass market sell steer by wire in the US last year, though I think they’ve only released one crossover with it

          I’m pretty sure that by “normal” car we were just talking about non-steer-by-wire cars. Maybe I misunderstood.

          Either way it was tested by some manufacturers in the past and if I remember correctly users generally disliked either the feeling or the simple knowledge that they have something between them and the wheels. We’ll see

    steer by wire and brake by wire are both dumb and i can’t fathom why its a thing at all. one electronic failure and you are in the ditch.

    The only problem I see is that the insufficient force feedback lets the steering wheel turn faster than the front wheels can turn, giving the driver wrong information. Only on a race track would you need to change directions that fast, and that’s standing still when turning resistance is immense, so it’ll turn even faster at speed. I doubt normal cars could turn the front wheels that fast standing still.

      You are not educated on professional driving. It’s part of any DOT regulated vehicle to not have more than an 1/8th of play in any steering wheel. The lag of any possible driver inputs is deemed by international regulations to down a vehicle and refuse to use it in any capacity until it is fully functional.

      You just said “No big deal. Fuck them laws.” to almost every person that has driven any sort of vehicle as a profession and what they have worked for decades to make it safe for everyone on the road.

    Ist this the equivalent of turning a regular power steering wheel like three complete turns (from on extreme to the other). Is that lag really an issue in real world use?

        Oh you are right of course, I am an idiot.

        I can see how that also can cause more damage as you will turn it even move within that split second where you don’t get a reaction from the car. This steering system is stupid as hell.
