I'm suspicious of any physical control being replaced with anything touch sensitive.

I'm largely there with you... I've frankly always had mixed feelings about it. Nothing like having your brakes or steering lose pressure while driving down the highway. That said, steering without at least hydrolic/power assist is rough on your forearms.

  A vehicle setup without power steering is a lot different than a vehicle with inoperative power steering. For one thing, they usually give you a bigger wheel, which helps with leverage. Power steering enables different steering geometries which likely wouldn't have been put together on a vehicle without power steering also. Exclusive brake by wire and/or steer by wire seem like they will add confusion and delay, and perhaps increased risk of injury when dealing with disabled vehicles. At least in my life, it's been pretty handy to be able to get a non-responsive vehicle into neutral and push it to somewhere else in order to get it out of the way of traffic or to have better access to repair it. That often means using the vehicle steering to help direct it to a good spot, and the vehicle brakes to stop it when it gets there. Accelerator-by-wire is more acceptable, as vehicle without working electrics doesn't need a working accelerator pedal; I have driven one vehicle with what I assume was drive by wire with significant latency, it wasn't enjoyable, but it was usable.

waiting for... doesn't work when feet are wet. Honestly, I think *-by-wire technology can exist, but I don't think it should be trusted to cost-reduction-at-any-cost manufacturers. I've heard the cybertruck steer-by-wire has a control lag. And then there's the no-mechanical-escape door handles.

  I have throttle-by-wire on my motorcycle and I love it. Very precise and safe.

      There's a decent amount of lag (delay between application of a force by the user and force at the throttle) and non-linearity in a 2-foot cable caused by elasticity of the cable and the cable guide and friction between the cable and the guide.

What sort of motorcycle was this? The ones I had had metal cables; there is no elasticity (if it stretches, it ain't shrinking - you'll adjust it to take up the slack). Friction between cable and guide also doesn't cause lag. (Still want to know how it is more safe)

        By "elasticity" I mean any change in length in response to a tensile or compressive force. A thin steel cable is quite elastic in response to the forces on it in this application (i.e., a lot more force than you can apply to the cable with your bare hands). Friction causes the force at the brake to be non-linear (and importantly unpredictably so) in the force applied by the user. If you had said that this elasticity and this non-linearity (and unpredictability) are small enough to be irrelevant in a properly designed motorcycle, I would have no way to contradict you: I don't know enough. But GGGP's comment[1] is evidence that they are large enough to be relevant. [1] "I have throttle-by-wire on my motorcycle and I love it. Very precise and safe."
