This is a preview from our weekly newsletter. Each week I go ‘Beyond the News’ and handcraft a special edition that includes my thoughts on the biggest stories, why it matters, and how it could impact the future.
Tesla’s strong financial spreadsheet that has culminated in seven consecutive quarters of profitability has launched the electric car company into a more stable fiscal situation. For years, especially in my early days at Teslarati, I can remember the big narrative being Tesla’s Quarter-over-Quarter growth, but the fact that profitability wasn’t achieved very often made the company one of the more risky investments at the time.
Since then, Tesla has managed to work out a profitable quarter seven times in a row. Unbelievably, the company that has only been mass-producing vehicles since Summer 2017 is already a shoo-in for money-making quarters, at least that’s what it seems like. There never seems to be a glimmer of doubt when it comes to Tesla reporting strong financials. But, it became clear earlier this week that Tesla, despite having such strong financials quarter after quarter, isn’t willing to spend money on things that owners and customers don’t use. The company’s phase-out of the passenger lumbar support feature in the Model 3 and Model Y is a prime example of the way Tesla is simplifying its vehicles to improve profitability and margins, making their cars even more of a money-making machine than they were previously.
On May 31st, a tweet from @Ryanth3nerd showed his discontent for Tesla’s removal of the lumbar support option on the passenger’s seat. It was noticed by a Model Y owner on Reddit initially that the lumbar support option was removed from the side of the seat, only leaving the reclining option and seat adjustment levers for passenger adjustment.
“I really don’t like the direction @tesla is going raising prices of vehicles but removing features like lumbar for the Model Y. On top of rumors of FSD increase to $14k without any real added features to FSD unless you’re a beta tester,” the tweet said.
It is true that Model 3 and Model Y prices alike have increased in the past several months. This is likely due to the semiconductor or microcontroller shortage that has plagued much of the automotive industry for the past few quarters. Additionally, Musk said raw material costs are also affecting Tesla’s prices.
According to Musk, Tesla had a good reason for phasing out the lumbar support module, and it had to do with data usage logs that showed the lumbar support wasn’t utilized by passengers very often. In fact, it was used so infrequently that Tesla decided to scrap the module altogether in the 3 and Y.
“Moving lumbar was removed only in front passenger seat of 3/Y (obv not there in rear seats). Logs showed almost no usage. Not worth cost/mass for everyone when almost never used. Prices increasing due to major supply chain price pressure industry-wide. Raw materials especially.”

Now, while this is a good point for Tesla to use as justification for their seat modification decisions, there are a few things that sort of confused me about the decision. First off, once a seat is adjusted, I think very few people want to change it. I know that when I get into a friend’s car, I rarely adjust the seat because that is probably the way their significant other prefers the seat to be set. As a driver in my own car, I know that I have only adjusted my seat on two or three occasions since I got it. Very rarely does it move, because the adjustments I made when I bought it were how I felt it was most comfortable, so I didn’t move it.
I think there could have been some confusion about whether the lumbar support is actually used, or whether it is a “set and forget” type of reasoning. I think many people find the way they like their seat, and it rarely changes over the course of the ownership experience.
While I doubt too many people will not buy a Tesla because they can’t adjust lumbar support, I think that there are some people who will look at it as a real disadvantage because there are plenty of people who need to utilize it for comfortability, especially if they have back problems. Nevertheless, it could be a temporary removal if enough people raise concerns to Musk via Twitter.
The biggest lesson here seems to be that Tesla’s use of data and analytics gives the company an extreme advantage when it comes to saving money on even the most trivial of parts. While Tesla will save some money from its recent decision to not equip Model 3 and Model Y cars with radar, the lumbar support removal also summarizes the company’s mission to take out what is not needed. Teslas are already so minimalistic as it is, and many people enjoy the lack of knobs and buttons on the interior. However, this is one knob that many owners may not be happy not having, but it remains to be seen if it saves Tesla’s enough money to justify keeping the feature left out from its two mass-market vehicles. -JK-

SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.

It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u

The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
