Tesla has formally started rolling out FSD Beta 10.1 with software update 2021.24.17, and while initial impressions seem to be largely positive, observations from the company’s testers are suggesting that the newest iteration of the advanced driver assist system is not yet equipped with the highly-anticipated “Single FSD Stack” that Elon Musk has hinted at in previous months.
The excitement surrounding V10.1’s release was notable, especially as Tesla has just launched the highly anticipated “Request FSD Beta” button to more members of its fleet. Members of the company’s original batch of FSD Beta testers have noted that the V10.1 update was about 2.9 GB, and it seemed to be comprised mostly of under-the-hood improvements. This was echoed by several longtime FSD Beta testers, many of whom have been part of the program since October 2020.
Longtime FSD Beta tester Tesla Raj, for one, observed after a 14-mile trip that the driver-assist system’s behavior on the freeway was still nearly identical to the system’s previous iterations. Another longtime FSD Beta tester, James Locke, observed that Summon still had its previous quirks. These, at least for now, hint that Tesla is yet to move functions such as Summon and highway driving to a single FSD stack.
Musk teased such a move back in July when he noted that FSD features like Summon and Navigate on Autopilot with Automatic Lane Changes would be “sublime” with a single FSD stack. Musk did, however, also emphasize that transitioning Autopilot and FSD to a single stack requires massive retraining for the company’s neural networks.
That being said, the CEO also hinted that Tesla is making some serious progress with its shift to a single FSD stack, with Musk stating following the rollout of FSD Beta 10.0 that the highly-anticipated transition would release in V10.1 instead. Considering the initial observations of the company’s FSD Beta testers, however, this shift seems to have been moved back once more.
This is not to say that FSD Beta 10.1 is a disappointment, of course. FSD Beta 10 is already one of, if not the most advanced consumer-grade driver-assist systems on the road today. Elon Musk may not consider FSD Beta’s current performance that great in the grand scheme of things, but it is still leagues ahead of competing systems from rival automakers.
Ford’s BlueCruise, for one, is promoted as a hands-free driver-assist system, but a real-world test from automotive teardown expert Sandy Munro revealed that BlueCruise disengages when faced with minor curves on the freeway, with little warning to the driver. Mercedes-Benz’s DrivePilot, on the other hand, is promoted as an SAE Level 3 system that enables hands-free driving, but it is incapable of operating in rain, show, or at nighttime.

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.
