The move to steer by wire has been underway for a while. Actually used in specialty vehicles. Virtually certain to be used in purpose built AVs. No point in such vehicles to having a wheel or the steering linkages.
Once the linkages are gone the wheel serves no purpose and a joy stick would be much more sensible. In some instances on a convenient location to the driver or on a removal remote control. Voice or touch screen may also be offered where control is rarely needed by a driver.
It is likely that steer by wire would have been adopted in regular automobiles eventually. It is more efficient and might well be cheaper than the conventional steering systems. Initial implementations might well have maintained the steering wheel but likely that it would eventually disappear.
This is attempting to have three independent discussions that have nothing to do with each other.
AV’s do not require steer by wire.
Steer by wire does not require getting rid of the wheel. Nobody is complaining about the existence of a steering wheel. They will complain however if you replace it with a PlayStation controller. There is nothing to be gained, but a lot to be lost.

Actually they do. Best practices for an auto of any sort in this time frame call for steer by wire. And AVs will want the direct access of a steer by wire system. One may well leave the steering wheel in a conversion. But a clean sheet design will likely remove it.
Steer by wire does not require removing the steering wheel. But good human factors in a class 5 AV do. In general you do not want to create an illusion that one can overcome the robot on demand.
Sorry, but no. Given that Uber released zero details to the public, other than the dash cam videos, everything here is speculation. The crash report was high level and covered no tech. Even the court details are sealed.
Funny - if it had been a normal car the end result would have been the same. But, in that case, everyone would have been tearing the 'stupid cyclist' to shreds for her unsafe and potentially illegal crossing.
Debatable. I have looked at that video, and I'm pretty sure the results would not have been the same, had I been driving that car. That is based on my 40 plus years of driving and being involved in hundreds of similar incidents. In the video I could see the woman a good four seconds before impact. I would have reacted by immediately pushing the brake all the way to the floor, and sounding my horn, non-stop. I would hope that she would have reacted to the sound of my brakes and horn, and the combination of my reaction and her reaction would have been enough to avoid a collision. If she didn't react appropriately, I expect it might be impossible to avoid a collision in that situation, but I'm confident that it would still not have been fatal.
Again that is based on my 40 plus years of driving experience, including several incidents of bicyclists without lights riding into the path of my car at night. I didn't hit them, and I don't believe I would have hit this woman. But if I did hit her, I'm confident it would not have been fatal. The results would not necessarily be the same. This technology is a joke.

We're typing on a keyboard layout made popular in 1878 that has parallel rows but diagonal columns and was designed to prevent a typewriter that was obsolete 100 years ago from jamming.
I don't think you're going to overcome preference for a wheel. And, I think you'd be hard pressed to improve on it.
Why is a joystick more sensible? I've driven skid loaders that had two throttle arms (basically joysticks). I've driven boats that steered from the tiller. I've driven boats that had a steering wheel at the helm. I've been on boats that had joysticks and autopilots and used the joystick for docking. I've been on lawn tractors that have steering wheels. I've been on lawn tractors that have wheels and zero turns where you turn with two throttle arms. They're great for their own applications.
Wheel steering has its inherent advantages baked into human motor skills.

You have no idea what you are talking about. So stop acting like you have all the answers, but convince yourself if you like, no one here is listening to you. Until it is released in force on the public, where mistakes can be corrected, because people on the road will die as we are used as guinea pigs for there R & D department. No one knows how things are actually going to work just yet. But hey, have a nice day.

I have every idea of what I am talking about. Spent 30 years running large engineering groups on electronically controlled stuff. Personally driven all sorts of vehicles including autos, trucks, RVs, power and sail boats and light airplanes.
I am no expert on automotive but I do understand the art they are attempting to apply to automotive.
That there is a contingent that tries to make it all vanish is clear. There are always a few that stand up hard against progress.
But it is coming whether the opponents like it or not. First trucks and hire cars and limited use vehicles. But eventually everything.
My views on steering wheels etc. simply reflects the findings of Google Waymo. And it could break in other ways. But none of that makes any difference in the long term.

No we are not. There are no keyboards today that even remotely resemble that I learned to type on 70 years ago. Utterly different feel and stroke. The "to prevent jamming" origin of QWERTY has not been proven. Just a theory.
Steer by wire is purportedly more efficient and will be substantially cheaper in systems that do not otherwise require hydraulics. Simply a much simpler and cheaper implementation. As whether it can work watch the Airbus planes which replaced the standard aircraft yoke with one. And it also removes a piece of equipment that consumed considerable space and makes the dashboard more accessible.

Apples to Oranges. Airbus spent a lot of money and effort proving they didn't need mechanical cables. The cable system to work an airplane was fairly complicated. A steering wheel is not at all complicated.

Virtually all the modern airplanes are fly by wire. Aircraft have more reasons than an automobile to go FBW.
There are however lots of reasons why the standard steering systems will be replaced in clean sheet AV designs. May well not happen in conversions where an existing design is made into an AV. But clean sheet designs will likely go to SBW.
If enough people like the steering wheel it could survive as a marketing item. Basically a steering wheel can be rigged as a large limited function joy stick.

That the QWERTY was designed to be slower and inefficient is the theory, actually false. It is designed to allow faster typing while preventing jams from multiple keys mashed at once.
Just like your keyboard of today being different than your typewriter, the steering will be very different, yet work the same. Steering wheel on the left hand side that directs the car. Steer by wire is better. But just because you can implement a yoke or a joystick doesn't mean its better.
