Several Tesla Cybertruck owners are expressing concerns about the truck’s inability to accurately read speed limit signs and comply with traffic laws.

The first person to share his frustration is a Cybertruck owner from Pennsylvania who reports that his truck mistakenly interpreted the 25 miles per hour speed limit as 55 mph in a residential neighborhood.

He noted that the truck then rapidly accelerated to over 40 miles an hour before he intervened and took control from the self-driving software.

This is definitely not ideal, and the Cybertruck owner shared his thoughts on the Cybertruck Owners Club forum.

He writes…

“Come on, Tesla - Focus on Getting Speed Limit Signs Correct

I continue to be amazed, annoyed, and downright disappointed by how unreliable my Cybertruck is at “reading” speed limit signs (which it clearly doesn’t). Databases, map overlays, algorithms, shmalgorhythms - they don’t matter. As drivers, we are held accountable for the posted speed limit. Period!

Today, after turning from a light onto a two-lane road in a residential area with stop signs every few hundred feet, my Cybertruck decided that the speed limit was 55 MPH, despite passing just beyond the light past a clearly marked traditional 25-mile-an-hour speed limit. I had to disengage as it quickly accelerated to over 40 miles an hour.

It would’ve clearly gone to at least 55. I was in the standard profile. Even a novice driver would’ve realized that this stretch of road could never be 55 miles an hour.

It simply can’t be trusted to follow the speed limit. It’s been really off on local roads and on highway trips across multiple states. I know there’s a focus on getting from point A to point B, but I’d like to see more emphasis on adhering to the law during the trip.

On the positive side, I’ve been very impressed with its decision-making, except for its speed limit recognition. Of course, I hate the profiles as most people do; I’d prefer something more granular. But seriously, can’t we get to the point where it actually reads the speed limit signs? If not, how can we ever trust that this car can drive us safely, even with our assistance?

And for what it’s worth, I always keep my hands on the wheel and stay attentive. This is about the inability to reliably perform a basic skill set taught to all new drivers: following speed limit signs.”

The Cybertruck owner clearly seems frustrated by the truck’s inability to understand and follow the speed limit. However, looking at the comments, a lot of other Cybertruck owners share this frustration.

Some owners even expressed their wish that Tesla would allow them to revert to the 2023 version of the FSD software, before Tesla stopped letting drivers manually set their preferred speed limit.

Currently, Tesla offers five different driving profiles: Sloth, Chill, Standard, Hurry, and Mad Max. The vehicle chooses the speed limit based on the selected profile.

This means instead of using the steering wheel button to easily adjust the speed limit, as was possible with the V13 software, Cybertruck owners and all Tesla drivers are now forced to repeatedly change the driving profile to modify the driving speed.

This approach helps somewhat, but if the Cybertruck reads a 25-mph speed limit as 55 mph, no driving profile will allow owners to drive within the legal limit.

Several Cybertruck owners are frustrated with this issue and have shared their complaints.

One Cybertruck owner writes…

“Speed management is definitely a constant chore.”

A second Cybertruck owner writes…

I'm constantly toggling between chill, standard, and hurry to keep the speed appropriate. Near my house, there's a highway that frequently switches between 55 and 65mph. Most people drive 70 to 80. I keep it around 68, mostly driving in Chill, switching to Standard when Chill drops below 65. Standard always wants to go 72, so when it hits 68, I roll back to chill.

Sometimes I find myself switching frequently. When the speed drops from 65 to 55, if I'm on chill and going 68, it immediately switches to full regen to slow the vehicle to 58, so I have to switch up to hurry, then gradually back to standard, then chill to prevent this....

My rationale is that the AI will see the multiple driver inputs (punishment), which will add data points for review. I don’t know, but it’s better than disengaging every 30 seconds.

A third Cybertruck owner writes…

“If I could roll back to the 2023 FSD version 13 software, I probably would just for this.”

A fourth Cybertruck owner says…

“Geez... I think I can top all of you. Try this:

Take a 3-day drive across the country using FSD while your daughter follows you and your wife follows her in FSD. Holy slinky formation, Batman!

I almost wore out the scroll wheel on my truck trying to maintain a steady speed, any speed, between Maniacal Mayhem and Slothy McSlowerson.

For THREE DAYS!

I mean, it was fine and much better than having to sit there with both hands on the wheel the whole time.

But it was weird how, in SOME construction zones, Fluffy would follow the posted limit, and at other times she thought those cones were a racetrack.

And for the record, "Fluffy" refers to my Cybertruck and NOT my wife.”

Overall, a lot of Cybertruck owners seem to find FSD more stressful than driving manually. However, please let me know what you think in the comments.
