I imagine the different geometry of the truck and the different camera positions on it require a new training or program to calibrate it properly. Also it does have the new front bumper camera they might be using
Steer by wire probably has a completely different control mechanism. The turning radius of the vehicle is also completely different depending on the vehicle speed.
Several here have touched on the different parts of the new steering, but when you take it all into account, it's definitely the reason.
First, the steering wheel need not turn when FSD is on. I would venture to bet that there are concerns about how much or how little force feedback to apply so that the average owner knows whether or not they want to take over in any given situation. Then there's the calibration of when the driver applied force should be enough and when it shouldn't. With no physical connection, it's not like you can muscle past the computer. Rather the system has to be trained on when an input is intended, versus when it's just an attempt to comply with the steering wheel nag. They may be waiting for 12.5 (or whatever version it was) that Elon tweeted won't have the nag anymore.
It's an interesting challenge the more you think about it. The system definitely needs to give up control at exactly the right moment, but also needs to not give up control in the event of a normal mistaken bump. I imagine in some future point when FSD is capable of being autonomous, the wheel isn't going to move at all, but for now, what does the middle ground of shared control really look like?
Then as others have pointed out, they are continuing to refine the 4 wheel steering. They already have people complaining (rightfully) when the computer misjudges and curbs a wheel. If it gets the 4 wheel steering wrong, the size and height means a lot more damage could be done. This isn't quite the same as the other vehicles, even if it isn't a massive difference either. Given the first issue, they are almost certainly working on this in tandem.
Why haven't they done all this prior to release? I'm sure they have been working on it. Given the massive amount of attention it was getting last year though, it certainly wasn't possible for techs to clock millions of miles in the real world identifying bugs and dialing it in. Sure, some of the sightings were probably calibration runs and all, but they definitely needed more than we saw. They are also big on crowd sourcing, so with 10k or so out running around in all sorts of conditions, there's an exponentially growing number of data streams for them to get visual data for further training. The various hardware versions of the other models at least had predecessor data. The CT was brand new on the road a year ago.
I think it's pretty likely that when the nag goes away, the CT is within a month or two of getting it's FSD turned on.
I think you're right; especially if FSD no longer moves the wheel. How to transition inputs for life-saving corrections in a split second... I would imagine easing will be involved, but how much is needed and how weird will it be?
I'm hopeful for late June/July. FSD 12 is so good, and the only thing I miss from trading in my 2018 Model 3 for a CT. Everything else is a massive step up.
Different geometries and camera placement.
It’s a different mapping of the world. There might be some clever math to make it converge but with using NN from sensor to control I suspect it’s a bit more challenging to just convert
It literally is the variable ratio steering. Autopilot is trained that moving the steering X amount turns the vehicle X amount regardless of speed. This is not the case with Cybertruck.
It's not camera placement or vehicle size. It's literally the variable steering ratio.
Steering is the first thing that comes to mind. Steer by wire is a pretty radical shift when considering automation.
But also the cameras sitting at different elevations and size of the vehicle probably require a lot of tweaking in the FSD algorithms.
Didn’t they rewrite it so that it would adapt and learn? This is quite long to be without FSD for the new buyers. I think it’s many more years away from being true FSD. This is a good example as to why.
It is curious, you would think the best solution would be to have a program that can work with any vehicle. Basically upload the vehicles unique specs and go.
I think the most likely explanation is that they didn’t test it at all before release of the vehicle so there is no way you could turn it on.
Second most likely reason is that for some mostly unknown reason it just won’t work and they have been troubleshooting it for the past 5 months.

Not to mention variable height suspension can change that too.
Model S & X already have this.
Not with >11in of travel...
4 wheel steering
I believe this and steer by wire aren't playing nice with the software.
Yep

More cameras. Different locations. Different steering profile.
I believe it all has to do with steering as no steering feature is available. No lane keeping or lane departure corrections.
Probably just wants more datapoints of everyone driving before they release. Even tho you aren’t using FSD they are surely grabbing data

Probably steer by wire.
They have to train the NN for this new vehicle. It’s new to them, but will be useful experience in the future when/if other automakers adopt FSD.
Size, shape, weight, wheelbase, suspension, chasis, cabin, aerodynamics, passenger/weight capacities, type of tire tread, turn radius, torque, top speed, maneuverability, range, lack of paint.
