Great info as always. I do remain a bit baffled why various robotaxi/AV companies are so enthusiastic about removing the steering wheel. Why would one ever take AWAY a feature from a car, and claim it is an improvement? The steering links will still be present, the electric steering motor and controller, and the steering column itself can be reduced and (as seen in your column) the wheel can be minimized and retractable. I think "no steering wheel" may go the way of "flush retractable door handles:" cool concept, minimal value. Imagine your robotaxi has crunched into a wall. Its autonomous systems shut down. Does the tow truck just drag it away from the wall, or pop up the steering wheel and manually guide it? Imagine your home garage is very narrow, such that in AV mode the car will not enter, due to collision alerts. Why not switch to manual mode and guide it in, carefully? Imagine you live in a northern climate, your spouse needs to get to the hospital, there is a blizzard and no "sane" AV stack will allow you to go anywhere. Why not switch to manual mode, pop up the wheel, and get going in this emergency situation? I repeat, I do not see the functional value of removing the wheel entirely, only the marketing value. I guess. Heck, even incredibly automated jet liners still have a primitive "tiller" for maneuvering around the tarmac.
