Tesla Autopilot update for better speed limit sign recognition is coming soon
Tesla CEO Elon Musk fielded several requests to address Autopilot’s ability to determine speed limit signs accurately, and the accuracy of its map data.
Amid reports that Autopilot users are still experiencing inaccuracies with the software’s ability to accurately read speed limit signs, Musk reassured users over Twitter that improvements are of utmost priority and an update is coming soon.
In the past, Tesla vehicles have displayed issues with recognizing Speed Limits correctly. Researchers at McAfee Advanced Threat Research managed to trick Tesla’s speed limit recognition technologies in the past by adjusting the appearance of the number “3” on a 35 MPH speed limit sign. This adjustment tricked the Tesla into thinking the speed limit was 85 MPH.
Yes, this is a high priority

Some owners on Tesla’s forums stated their vehicles had issues recognizing speed limit signs accurately. Sometimes, the car would not register a speed limit sign at all. The problem caused some owners to have their vehicles driving through zones at excessive speeds, causing a safety issue and risking them to receive a ticket.
One owner in the forum stated, “Was wondering why some speed limits signs are not recognized on my Tesla. Don’t need a ticket.”
It seems that some owners whose cars still utilize Mobileye and Hardware 1 are the only drivers whose vehicles recognize signs accurately the majority of the time. However, when Tesla and Mobileye ended a partnership in 2016, Tesla was forced to make its own software to recognize speed limits. Tesla vehicles manufactured after the partnership ended use GPS-based speed limit recognition and not camera-based identification.
Arguably one of the most substantial hurdles Tesla must jump through on its journey to autonomous driving features is the accuracy of sign recognition. Without the ability to read road signs and speed limits, the autonomous features are pointless because the vehicle will not function properly. Tesla’s Artificial Intelligence program is working diligently to improve the functionality of Autopilot, and it starts with accurate street sign recognition.
Coming soon

When Tesla’s Head of AI Andrej Karpathy spoke about the processes of identifying street signs, he explained that the vehicles depend on code to recognize instructions. The issue with this is that many states utilize different words or layouts to describe the same action. For example, Karpathy stated Tesla holds the most extensive set of “Except Right Turn” signs in its database. These signs often say the same thing but are different sizes, fonts, or shapes, all of which are factors that can spell trouble for a software system.
The improvement of accurately recognizing signs will move Tesla closer to finishing its Full Self-Driving suite. After Tesla released the Stop Sign and Traffic Light Control feature, only City Driving remains on the list of FSD features that have yet to be unveiled. Recently, the company also published its safety statistics, marking Autopilot’s safest year to date. With added improvements over time, thanks to the contribution of data to the company’s Neural Network, Tesla can continue to improve upon its already impressive FSD performance.
Tesla revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.
The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.
On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.
Tesla Cybercab has one important piece that AI4 cars might need for FSD
It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:
“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.
It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something
There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.
Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.
Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.
Here are the full release notes for the suite:
- Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
- Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
- Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
- Introduced parking, unparking, and reversing capabilities.
- Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
- Speed Profiles are now available at all times, to further customize driving style preference.
These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.
Tesla Full Self-Driving v14 ‘Lite’ for older cars finally gets released
He added:
“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”
FSD v14 Lite is now rolling out to AI3 early-access customers. Based on the feedback, will rollout to more customers over the next few weeks.

Tesla will continue to roll out the v14 Lite suite more widely in the coming weeks, the company said.
Tesla has finally released its Full Self-Driving v14 ‘Lite’ suite for older cars that equip the Hardware 3 or AI 3 chip, which have not been able to handle the newest versions of the company’s driver assistance software.
Tesla officially started releasing the v14 Lite suite to owners in the Early Access Program last night. The company’s Head of AI, Ashok Elluswamy, said that the rollout will continue over the next few weeks. The build distills the driving behavior from AI4’s v14 series into both the camera and compute configurations of an AI3 car.

It also includes a variety of new features that were available to AI4 cars running v14, including:
- Start Self-Driving from Park
- Arrival and Parking Options
- Speed Profiles
The release is highly anticipated because those owners with AI3 vehicles were early adopters into the FSD platform and were promised that their cars would be capable of achieving Full Self-Driving.
However, Tesla CEO Elon Musk admitted during the company’s recent Q1 Earnings Call that these vehicles would not be capable of achieving unsupervised Full Self-Driving, which is what Tesla had originally said.
Owners were not pleased with this answer, or the idea that their commitment to buying the suite outright for thousands of dollars would not yield the ability to drive without operating the car. Tesla gave some solutions for this, including a discount on a new car, or an upgrade to an AI4 or AI5 self-driving computer and new, upgraded cameras.
Tesla owners do not seem pleased with these options, as they require giving the company more money.
Nevertheless, it is important to note that Tesla came through for owners here by releasing v14 Lite before the end of Q2, something it had promised owners during the previous Earnings Call. Tesla has had trouble keeping up with timelines, but this is a big achievement for the team.
