Tesla Model 3-based ventilator critiqued by ICU nurse: “Very good job…well done.”
An Anaesthetics and Intensive Care Unit (ICU) nurse recently broke down Tesla’s video of its in-house ventilator system that is made from Model 3 parts.
YouTuber Chris Vanderstock is a nurse by trade and holds over 20 years of experience in a medical setting. His resume includes years of administering patients with real-life medical conditions anesthesia before surgeries and providing them with air via the operation of a manual resuscitator. Vanderstock has plenty of experience with critical care ventilators and how they operate making him a prime candidate to give Tesla’s engineering team relevant feedback toward its newly designed machine.
Vanderstock was initially impressed with Tesla’s utilization of its vehicle parts to create an efficient ventilator. “I reckon a good two-thirds of this ventilator is from existing parts that Tesla already has,” the veteran nurse said. After listing the parts that will be included in the ventilator, like the Model 3’s display, Vanderstock gave his kudos to the Tesla team. Tesla’s goal was to use primarily parts that it knew for reliability purposes, as well as not take away any parts from the medical community who are already struggling with providing hospitals with ventilators, to begin with.
The mixing chamber that is responsible for combining several gases to create breathable air for a patient who is having trouble breathing is a critical part of a ventilator. Along with the mixing chamber, several pressure monitors, along with volume sensors that will provide the patient with the correct levels of oxygen, are included in the Tesla ventilator. Vanderstock noted that this is one of the most crucial parts of a ventilator, as too much air into the lungs can overinflate them, causing more damage than there was initially. Tesla nailed this, according to Vanderstock. “Kudos to these guys.”
Perhaps one of the most exciting portions of the Tesla-made ventilator is the use of two filters, one on the patient end where air is distributed to a patient’s lungs, and one on the machine end, where the virus will be displaced as the patient exhales. This double-filter feature is a notable part of ventilators from Medtronic, a company that Tesla has been in talks with since late March. Vanderstock says the ventilator’s machine-end filter is crucial to keeping healthcare workers safe, as a non-filtered machine end could lead to the virus being spread to those in the room.
The only concern Vanderstock had about the ventilator was how Tesla planned to warm and humidify the oxygen that will go to a patient’s lungs. “When you are thinking about how we breathe, our nose, the turbinates, the structures behind your mouth, going down your trachea into your lungs, are all being warmed…by your blood supply. As air travels down, it gets warmed on the way, and obviously, you’ve got the mucosal layers that’s sending in a bit of moisture as well,” he remarked.
One of Vanderstock’s favorite features is the inclusion of the Model 3 dash screen that will display information like pressure and oxygen concentration to medical professionals. “The innovative infotainment system could potentially help patients. Very good job at Tesla, well done,” he said.
All in all, Vanderstock is exceptionally impressed with Tesla’s ability to create a ventilator that has such an effective manner in a short amount of time. “Nonetheless, great first effort,” he said.
While the machine will still have to pass through Food and Drug Administration (FDA) regulations, he believes this process could be expedited as ventilators are needed on the front lines of hospitals in some of the United States’ most prominent cities.
CEO Elon Musk has stated that ventilators, whether they are purchased or manufactured by Tesla, will be available for free with worldwide shipping as long as the hospital requesting the machines is in immediate need of them. Musk has already made over 1,200 donations to Los Angeles and New York City hospitals as the COVID-19 pandemic is expected to reach its peak this week, according to U.S. Surgeon General Jerome Adams.

Tesla CEO Elon Musk teased the insane capabilities of the next major Full Self-Driving update just hours after the company rolled out version 14.2 to owners.
Tesla Full Self-Driving v14.2 had some major improvements from the previous iteration of v14.1.x. We were on v14.1.7, the most advanced configuration of the v14.1 family, before Tesla transitioned us and others to v14.2.
However, Musk has said that the improvements coming in the next major update, which will be v14.3, will be where “the last big piece of the puzzle finally lands.”
14.3 is where the last big piece of the puzzle finally lands
— Elon Musk (@elonmusk) November 21, 2025
There were some major improvements with v14.2, most notably, Tesla seemed to narrow in on the triggers that caused issues with hesitation and brake stabbing in v14.1.x.
One of the most discussed issues with the past rollout was that of brake stabbing, where the vehicle would contemplate proceeding with a route as traffic was coming from other directions.
We experienced it most frequently at intersections, especially four-way stop signs.
Elon Musk hints at when Tesla can fix this FSD complaint with v14
In our review of it yesterday, it was evident that this issue had been resolved, at least to the extent that we had no issues with it in a 62-minute drive, which you can watch here.
Some owners also reported a more relaxed driver monitoring system, which is something Tesla said it was working on as it hopes to allow drivers to text during operation in the coming months. We did not test this, as laws in Pennsylvania prohibit the use of phones at any time due to the new Paul Miller’s Law, which took effect earlier this year.
However, the improvements indicate that Tesla is certainly headed toward a much more sentient FSD experience, so much so that Musk’s language seems to be more indicative of a more relaxed experience in terms of overall supervision from the driver, especially with v14.3.
Musk did not release or discuss a definitive timeline for the release of v14.3, especially as v14.2 just rolled out to Early Access Program (EAP) members yesterday. However, v14.1 rolled out to Tesla owners just a few weeks ago in late 2025. There is the potential that v14.3 could be part of the coming Holiday Update, or potentially in a release of its own before the New Year.
Tesla rolled out Full Self-Driving version 14.2 yesterday to members of the Early Access Program (EAP). Expectations were high, and Tesla surely delivered.
With the rollout of Tesla FSD v14.2, there were major benchmarks for improvement from the v14.1 suite, which spanned across seven improvements. Our final experience with v14.1 was with v14.1.7, and to be honest, things were good, but it felt like there were a handful of regressions from previous iterations.
While there were improvements in brake stabbing and hesitation, we did experience a few small interventions related to navigation and just overall performance. It was nothing major; there were no critical takeovers that required any major publicity, as they were more or less subjective things that I was not particularly comfortable with. Other drivers might have been more relaxed.
With v14.2 hitting our cars yesterday, there were a handful of things we truly noticed in terms of improvement, most notably the lack of brake stabbing and hesitation, a major complaint with v14.1.x.
However, in a 62-minute drive that was fully recorded, there were a lot of positives, and only one true complaint, which was something we haven’t had issues with in the past.
The Good
Lack of Brake Stabbing and Hesitation
Perhaps the most notable and publicized issue with v14.1.x was the presence of brake stabbing and hesitation. Arriving at intersections was particularly nerve-racking on the previous version simply because of this. At four-way stops, the car would not be assertive enough to take its turn, especially when other vehicles at the same intersection would inch forward or start to move.
This was a major problem.
However, there were no instances of this yesterday on our lengthy drive. It was much more assertive when arriving at these types of scenarios, but was also more patient when FSD knew it was not the car’s turn to proceed.
Can report on v14.2 today there were ZERO instances of break stabbing or hesitation at intersections today
It was a significant improvement from v14.1.x

This improvement was the most noticeable throughout the drive, along with fixes in overall smoothness.
Speed Profiles Seem to Be More Reasonable
There were a handful of FSD v14 users who felt as if the loss of a Max Speed setting was a negative. However, these complaints will, in our opinion, begin to subside, especially as things have seemed to be refined quite nicely with v14.2.
Freeway driving is where this is especially noticeable. If it’s traveling too slow, just switch to a faster profile. If it’s too fast, switch to a slower profile. However, the speeds seem to be much more defined with each Speed Profile, which is something that I really find to be a huge advantage. Previously, you could tell the difference in speeds, but not in driving styles. At times, Standard felt a lot like Hurry. Now, you can clearly tell the difference between the two.
It seems as if Tesla made a goal that drivers should be able to tell which Speed Profile is active if it was not shown on the screen. With v14.1.x, this was not necessarily something that could be done. With v14.2, if someone tested me on which Speed Profile was being used, I’m fairly certain I could pick each one.
Better Overall Operation
I felt, at times, especially with v14.1.7, there were some jerky movements. Nothing that was super alarming, but there were times when things just felt a little more finicky than others.
v14.2 feels much smoother overall, with really great decision-making, lane changes that feel second nature, and a great speed of travel. It was a very comfortable ride.
The Bad
Parking
It feels as if there was a slight regression in parking quality, as both times v14.2 pulled into parking spots, I would have felt compelled to adjust manually if I were staying at my destinations. For the sake of testing, at my first destination, I arrived, allowed the car to park, and then left. At the tail-end of testing, I walked inside the store that FSD v14.2 drove me to, so I had to adjust the parking manually.
This was pretty disappointing. Apart from parking at Superchargers, which is always flawless, parking performance is something that needs some attention. The release notes for v14.2. state that parking spot selection and parking quality will improve with future versions.

However, this was truly my only complaint about v14.2.

SpaceX issues statement on Starship V3 Booster 18 anomaly
The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX has issued an initial statement about Starship Booster 18’s anomaly early Friday. The incident unfolded during gas-system pressure testing at the company’s Massey facility in Starbase, Texas.
SpaceX’s initial comment
As per SpaceX in a post on its official account on social media platform X, Booster 18 was undergoing gas system pressure tests when the anomaly happened. Despite the nature of the incident, the company emphasized that no propellant was loaded, no engines were installed, and personnel were kept at a safe distance from the booster, resulting in zero injuries.
“Booster 18 suffered an anomaly during gas system pressure testing that we were conducting in advance of structural proof testing. No propellant was on the vehicle, and engines were not yet installed. The teams need time to investigate before we are confident of the cause. No one was injured as we maintain a safe distance for personnel during this type of testing. The site remains clear and we are working plans to safely reenter the site,” SpaceX wrote in its post on X.
Incident and aftermath
Livestream footage from LabPadre showed Booster 18’s lower half crumpling around the liquid oxygen tank area at approximately 4:04 a.m. CT. Subsequent images posted by on-site observers revealed extensive deformation across the booster’s lower structure. Needless to say, spaceflight observers have noted that Booster 18 would likely be a complete loss due to its anomaly.
Booster 18 had rolled out only a day earlier and was one of the first vehicles in the Starship V3 program. The V3 series incorporates structural reinforcements and reliability upgrades intended to prepare Starship for rapid-reuse testing and eventual tower-catch operations. Elon Musk has been optimistic about Starship V3, previously noting on X that the spacecraft might be able to complete initial missions to Mars.
