Since it’s Steer By Wire it could Crab Walk — right?

Did anyone ask about current or upcoming Crab Walk ability for Cybertruck?

My understanding is that over a certain speed the wheels move in unison to improve handling. I would imagine it would be simple to program the truck to do this at lower speeds if one wanted to show the truck doing a "crab walk" for a Youtube video and zero other utility!

I didn’t know that. I think I heard that rear wheel steering (to reduce turning radius) only occurred at lower speeds. So, for lane changes it just kind of slides in?

Seems like a gimmick, no?

I'm more interested in migrating the steering portion to an RC Car remote and setting up a throne in the truck bed.

The Cybertruck crab mode has already been demonstrated a few days back in one of the Giga-Texas videos.

Maybe? Possible it’s a TM issue, and legal is working through the upcoming announcement of “Cyber ShimmyTM”

I did see that video, but the crabbing was so brief I wasn’t sure it was really controlled by the driver.
In this CARWOW video the Cybertruck is taunted by a Hummer EV (who crabwalks), and even though a Tesla engineer was present, there didn’t seem to be a way for the user to make CT to do it, as might be used for parking. The tauntation occurs at 5:00 in the video. Link:

Well, we know that the rear wheels have a 10 degree limit according to one of Sandy Munro's recent videos, so I guess it won't crab to extreme. But I was just pointing out the basic feature. I'm also interested if crab mode will be a software integrated feature activated in some trailer backing assist modes because I think that would be useful. If they aren't yet, they certainly could with a software update (another good thing about the steer-by-wire).

But, I wouldn't care if the Hummer could 'crab' circles around the Cybertruck, because it's 2600 pounds heavier and grossly inefficient compared to the Cybertruck, as pointed out in Jason Camissa's recent video, which I think is one of the best ones out there.

That’s for sure! I’ve been hoping for that and really curious about how trailer-backing would be controlled… probably best if the CT calculates the best path and is aware of the trailer’s size and axle distance. It would be impressive to watch.

I had dismissed crab walk as a useless gimmick but it could totally be useful for hooking up a trailer..

Well crap, now legal has to start over.lol

Also useful for certain parking or lane changes. Tesla has made it integral with the software for most situations. But the opposite of crab is also most useful because it reduces the turning radius by a lot.

There's also another good reason for steer-by-wire also. Steer-by-wire makes it easy to create right-hand-drive Cybertrucks for overseas markets like Australia, because Tesla only has to move the steering wheel assembly inside. Nothing outside the interior even needs to be changed (except the BAW). Many times much easier to manufacture.

Troy,
The beauty of 4WS is the ability to change the rear wheel steering in phase or out of phase with the front wheels. At high speed, an emergency evasive maneuver can cause loss of control as the rear end loses traction and tries to pass the front end. By turning the wheels in the same direction, you minimize the tendency to “fish tail” the rear end during such an abrupt maneuver. Also, when towing, it is far more stable. So just as there is more front wheel angle change at low speed vs high speed, there is a change to the rear wheel steering based on speed.
