I know the logic behind it is that they are allowing for adaptive steering based on vehicle speed. So at parking lot speeds, you can turn the wheels to full deflection while keeping both hands on the wheel, then a typical steering ratio at highway speeds.

There are plenty of potential benefits.

But compare that to the REALLY obvious possible flaws.

Well put. There are indeed some more knobs a clever designer could turn with such a setup. The gains, in my opinion, are not worth the risk. You can make a clever steering box and assist program, and you don't miss out on some of those benefits. Everything is a compromise, but this one seems like a big safety risk, and I am sure it's not the right company to do it. I wasn't sure Boeing could pull it off, given their lack of risk mitigation lately.

Still need some kind of actuator to turn the wheels. The rack is a pretty efficient way to make that motion.  Even without a steering column input, the mechanism to turn the wheel direction is pretty simple and light.

Have any of these incidents been verified and positively determined to be anything other than driver error?

Or is this all about sensationalism and wild conjecture?

The incident linked above is of a guy who bought a Cybertruck and had its steering fail while he was driving with his family, as he himself reported. He still loves the company and the truck... somehow.

I don't know, but you do raise a good point. Telsa is a lightning rod (pun intended) for criticism. Everything they do gets 100x the coverage of anyone else's. When there are fires, you hear about it, even though ICE vehicles are more likely to catch fire. When there are incidents with autonomous driving,  you hear about them, even though plenty of others have had them. Then again, they get a ton of free publicity that way, too. It's a double-edged sword for sure.

Even so, a lawyer tweeting "I crashed because my steering and my brakes failed" falls well short of being authoritative proof of a malfunction.  What was his BAC at the time?

What manner of proof would you like, exactly? Is this a jury?

Ever since the "spontaneous acceleration" debacle color many of us cynical IRT such claims.

The linked incident is reported to be a steering issue, but the valet crash noted, was apparently the driver blaming the valet (so he might be terribly trustworthy).  There was also another similar crash I saw on the news (months ago) with a know actor in a Lucid (?) that was sitting at a red light and suddenly plowed through the car in front of it into a curb across the intersection (there is video).

I am wondering if the two (non-linked) incidents what might a sort of Audi style "unintentional acceleration" thing going on.  Obviously with the insane acceleration of some of these, even a bit of a slip up can create a huge issue.  Not sure there is anything in the basic characteristics of these cars that would increase that likelihood other than lots of power.

It should be noted of course that when people do stupid things, they tend to try to come up with an excuse as to why it's not their fault.  The actor claimed he did nothing and the car accelerated.  In most unintended acceleration cases, the driver thinks they are pressing the brake, so they just press it harder when the car starts accelerating.

Do these cars have a particular feel to their accelerator or brake that might be different from a typical car?

Found the actor incident.  Looks like the police are blaming his unfamiliarity with its features, whatever that means (there is a better video than the one they show in the link below):

Alan Ruck's Rivian R1T crash due to unfamiliarity with tech, police say

No evidence of DUI or distraction

On Halloween night, actor Alan Ruck's Rivian R1T pickup crashed into a California pizza parlor. The electric truck suddenly accelerated across an intersection through a red light, damaging three other cars before smashing through the wall of the restaurant. Police are now reportedly saying that the crash was likely due to Ruck's unfamiliarity with the new truck's high-tech features.....

Not sure I trust him. He once kicked his father's classic Ferrari until it reversed through a glass wall.
