Opinion: Where would Herbert Diess fit best (hypothetically)?
Herbert Diess is officially no longer a Volkswagen employee, effective Wednesday. The seven-year reign as CEO and Chairman of the Board of Management came to somewhat of an abrupt end after Diess and VW decided to part ways at the end of August.
“These were the most rewarding seven years of my career. The future of our industry can be brilliant, but we have to change fast. Volkswagen has already changed tremendously and is well underway,” Diess said. “We have transformed the company that was seen as an autocratic cheat into a global thought leader in clean mobility.”

Diess’s future remains in question, and while retirement is the likely option, there are several routes that he could potentially go, barring any stipulation in his contract that would eliminate the possibility of working for a competitor. While it is a long shot, Diess has three main automakers he would likely benefit from almost immediately, making an impact on several companies as his proven track record speaks for itself.

While I have already been in numerous discussions with various people about this possibility, and even though it seems unlikely, the first company that Diess would benefit is Tesla. Not only does Diess share a friendship with Elon Musk, but he could also benefit Tesla’s European business with additional expertise on the market. VW has performed very well in Europe in terms of EVs, and helping Tesla expand its operations throughout the continent would likely be a huge advantage for the company.
Tesla undoubtedly has a bright future in Europe, but Volkswagen currently holds the EV title there. The AG owned 1/4 of the European plug-in market in 2021, according to CleanTechnica data.
Toyota
I believe Diess has the track record to be a considerable ally to Toyota. Why? Toyota and VW have a lot of parallels, and Diess would likely navigate through them with considerable success.
Toyota is the world’s largest automotive manufacturer by volume, and it has been for some time. The last time a major automotive manufacturer outproduced Toyota was when GM built nearly 1M cars more than the Japanese company in 2011. Even VW finished ahead of Toyota in terms of production that year, but it has been a masterclass in production ever since.

Volume is not the only way the two companies are somewhat similar. EV development is also somewhat of a parallel. VW has coming out of the Dieselgate crisis and had to make major waves to regain consumer trust. Diess knew this, and pushed incredibly hard for several years to help VW reinvent its reputation as a sustainable company. Toyota really needs the same thing.
Although it isn’t going thru an emissions scandal, Toyota has basically half-committed to EVs, aiming to go toward hydrogen and hybrid vehicles instead. It is not to say that the company hasn’t contributed to sustainability in other ways: the Toyota Prius was a huge step forward in sustainable transport. Evolution needs to continue, however, and it is time for Toyota to really begin developing some high-tech EVs. They’re falling behind, and Diess, with his experience in high-volume companies and sluggish EV plans, is a good fit.
General Motors
GM would also be a good fit for Diess simply because of his push and determination to transition a company quickly. GM is honestly a company that has so much potential, but it feels like they’re falling just short of the mark in so many areas. The Bolt has plagued GM with bad advertising for several years, the HUMMER EV is having more issues than what were anticipated, and the company’s plans for electrification seem to be one drastic announcement followed by silence and promises that they’ll one day overtake Tesla.
While Tesla dominates the industry now, it will eventually take a few decades for others to catch up, and they likely will. However, Tesla is establishing itself as the leader and it is no secret. It is going to take a long time to figure out the tech and the manufacturing and the supply chain.

GM will likely catch up to Tesla, but it won’t be in the 2020s or 2030s. They’ll all even out, just as the market is now. A lot of car companies do a lot of business, and it’s only a matter of time before other companies begin to figure things out.
GM will absolutely be a true player in the EV industry, and it’s just going to take some time. This is where I feel Diess would be a considerable asset to GM, simply because he emphasized on accelerating VW’s transition to sustainable energy. The goals of 2035 or more were simply not going to work. Things needed to be figured out now, and the goal is to establish yourself as an early player in the disruption of a sector. VW has done that thanks to Diess, GM has announced more (at least to me) but accomplished considerably less.

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.
