CT in Service - MX Plaid Loaner (FSD Comparison)

[Texas25CT]

So my Cybertruck was in the service center today for the tonneau cover slat fix. Tesla gave me a Model X Plaid as a loaner for the day.

I have, every chance I get, used FSD in my CT and when it works great, it’s GREAT! However, it is never perfect the entire drive and will do a few things that I’m not fond of:

- Hug the left side of the lane (center lane in the right and yellow when in the left lane)

- Take turns faster than what’s expected or normal

- Slow down very late upon reaching a red light behind another vehicle or if the vehicle in front of me is starting to slow down (regardless if their brake lights are active or not)

I typically drive in a custom profile normal acceleration, softer suspension and prefer high suspension. But I believe FSD switches to the comfort profile… I think that’s what it’s called.

When using FSD in the Model X everything I just listed was fixed. It even felt as if it was more confident and it drove phenomenally! I let it drive me completely all the way home through the crazy Norfolk/VA Beach traffic and to the most southern part of Suffolk. If I dared to do this in my CT, I’d have to disengage and reset multiple times because of the issues I’ve listed.

Is anyone else encountering these issues? And do you have experience with FSD in other cars and can say it’s like way better?

both cars were on the same software version and FSD version.

The CT still doesnt have it's own FSD. It's using a modified version from the Model Y. Eventually they will deliver the full experience of FSD to the CT.

Yes the other newer cars are better on FSD. I just got a new Y and it is on another level than the Cybertruck FSD.

My 2020 Model Y LR (HW3+Intel Atom) has better FSD than my 2024 FS AWD, along with having A.S.S too.

CT is your first Tesla, huh? Yeah, the sexy cars do better. They have a ridiculous amount of them on the road to provide tons of efficient inference compute. CT only has, well, us. We’ll get there, but we all need to keep FSDing our trucks as much as we can.

I’d say CT does a little better than my HW3 at this point, but it’s true ASS is a big thing.

That’s the first I’m hearing that! Where did you hear that? I guess that would explain the right side being centered and the left side not….

It is my second. My wife was the guinea pig and we got her one of the last legacy ‘25 MY LRAWD in our area. FSD, when she had it, was great too. Definitely not as polished as the MX I drove today though. That was completely on a different level.

I agree though. It does need more training and I attempt to use it whenever I can. When my daughter starts school back up, it’s a fairly straight line drive with one traffic circle, 1 left and 1 right turn so I’m gonna be using it daily back and forth there.

My hw3 plaid is way better in almost every measure than my cyber. Low sales, we aren’t going to get the resources and it sucks.

@Texas25CT yes this FSD experience is the same with my Cybertruck and my Model Y, both 2023 and 2026 versions. Pretty much a universal experience...

Wes, the lead engineer for the CT, said it a while ago. Everyone was waiting for start FSD from park, reverse, ASS, park at the end of the drive, and other features left off the CT as confirmation of the CT having it's own stack, but with RT launch, no one has had any FSD love. Hopefully we get some in September.

My wife's 26 MY Launch Edition has FSD, and it is vastly superior to the FSD in my '25 AWD CT. Not even close. We can trust the MY to essentially be a private driver, from driveway to destination, no interaction. The CT makes multiple mistakes before even leaving the neighborhood, and of course, cannot start FSD from parked. That's the least of its issues, but is emblematic of the CT's FSD development status vs the MS, MX, MY and M3.

It is obviously unique to the CT - the vehicle size alone requires this, as does its unique sensor/camera layout and related dimensions. Weight, steering, and braking are also quite different, so how it operates must be unique to the CT - even things as simple as speed bumps will operate differently between the CT and MY. And what we have is at least a generation behind the current MY FSD. Further, the CT has drive-by-wire, and the MY does not. Ergo, the CT requires its own FSD version.

Impossible for me as most of my CT miles are towing, and FSD will not operate.
