In the early hours of July 10, 2026, Tesla started pushing firmware update 2026.21.100 to an initial cohort of owners in the Netherlands. The over-the-air package delivers Full Self-Driving (Supervised) software version 14.2.2.6, making it the first time the advanced driver-assistance system has officially reached European roads.
A long-awaited European debut
The firmware update—2026.21.100—is the vehicle that carries FSD v14.2.2.6, a point release within Tesla’s fourteenth-generation city-streets stack. While release notes are not yet public, the version number alone signals a mature, refined build. The “Supervised” designation means the system still requires a licensed, attentive driver behind the wheel who is ready to take over at any moment. For the Dutch owners receiving the download, this marks a tangible step beyond the Autopilot features they have used for years: for the first time, their cars can attempt to navigate complex urban environments, from unmarked intersections to roundabouts and tram tracks, without explicit lane markings.
Tesla has not yet posted an official blog or support article about the 2026.21.100 release, so the precise set of capabilities enabled on Dutch streets remains to be confirmed. Based on what is known about FSD v14 in other markets, owners can expect the system to handle automatic lane changes, traffic light and stop sign control, and point-to-point navigation on surface roads. However, localisation—verifying that the neural networks have been trained on enough Dutch-specific driving data—will determine how smoothly it performs out of the gate.
What it means for you
For the select group of Tesla owners in the Netherlands who are part of the initial push, the experience begins immediately. Cars enrolled in the Advanced software update preference will download the firmware automatically when connected to Wi‑Fi. The first drive after installation will likely feel like a science-fiction moment: the car steering itself through Amsterdam’s narrow canal-side streets, yielding to cyclists, and interpreting local traffic signs. Yet, the reality of a Supervised system is that the driver must stay fully engaged—hands on the wheel, eyes on the road—and be prepared to disengage if the vehicle hesitates or misreads a situation. This initial rollout is essentially a public beta, and the drivers serve as de facto validators for the Dutch driving environment.
For the broader community of European Tesla owners, the Dutch premiere is a harbinger. The Netherlands has historically been one of Tesla’s strongest European markets and often acts as a beachhead for new features. If the 2026.21.100 release proves stable and receives positive regulatory signals, the rollout could extend to other EU countries within weeks or months. Owners in Germany, Norway, France, and the UK should keep an eye on their Tesla app and software settings, though no official timeline exists.
From an administrative perspective, fleet managers and IT departments that oversee corporate Tesla vehicles now have a new variable to account for. FSD v14.2.2.6 may introduce behavioural changes that affect route planning, energy consumption, and safety protocols. Those managing pools of Tesla cars will want to communicate clear usage policies and potentially delay updates on fleet vehicles until the initial feedback is in.
How we got here: seven years of FSD evolution
Tesla’s pursuit of full self-driving capability has been a winding road. The company first announced its “Full Self-Driving Hardware” suite in October 2016, claiming that every new Tesla would have the sensors and compute necessary for autonomous driving. Software, however, lagged by years. Early Autopilot and Enhanced Autopilot features handled highway driving, but city streets remained elusive.
In October 2020, Tesla released the first limited beta of “Full Self-Driving City Streets” to a handful of US employees. Over the next five years, the system went through eleven major version numbers—numbered V9 through V12—each rewriting core modules. V9 introduced a new vision-based approach. V10 brought more confident lane changes. V11 unified city and highway stacks into a single neural network, while V12 famously replaced thousands of lines of traditional C++ code with an end-to-end AI model trained on millions of real-world drives. That V12 rollout, which started in early 2025, earned praise for markedly smoother stops and more human-like decision making.
FSD v14, of which 14.2.2.6 is a sub-version, is understood to incorporate further architectural improvements, likely involving a larger model size and additional real-world training data. The leap from V12 to V14 suggests significant under-the-hood revisions. As with all Tesla software, continuous data collection and over-the-air updates mean that today’s 14.2.2.6 build will evolve rapidly, with point releases correcting edge cases as they are discovered.
Europe’s delayed entry into the FSD era has not been due to technology alone. The continent’s regulatory framework—governed by UNECE regulations and European Union type-approval rules—proved more restrictive than the US environment. Automated lane-keeping systems, for instance, faced tight speed limitations and required explicit approval. Tesla had to work through national type-approval authorities, particularly the RDW in the Netherlands, to demonstrate compliance. The Dutch initial cohort suggests that these regulatory hurdles have now been cleared, at least for a supervised system that keeps ultimate responsibility with the driver. It is a watershed moment for the European ADAS landscape.
What to do now
If you are an owner in the Netherlands and your Tesla has not yet been notified, be patient. Tesla’s staged rollouts often take several days to reach all eligible vehicles. To maximise your chances of early access, ensure your car’s software update preference is set to “Advanced” (found under Controls > Software > Software Update Preferences). Connect the car to a strong Wi‑Fi network overnight, as downloads are typically prioritised while the car is asleep.
Once the update arrives, take time to read the in-car release notes carefully. They will document any local limitations or known caveats. Before engaging FSD on a busy street, test it in a quiet residential area or an empty parking lot to build trust in the system’s behaviour. Pay close attention to how it handles cyclists, pedestrians, and situations unique to Dutch roads—such as the many priority intersections where the car must correctly determine right-of-way.
For those outside the Netherlands, there is no immediate action beyond ensuring your car’s software settings are also on “Advanced” and staying informed through official Tesla communications. Enthusiasm should be tempered with realism: a wider European rollout depends not only on the technical performance of this build but also on regulatory endorsements from other national authorities. Tesla will likely submit validation packages incrementally; countries with similar regulatory environments to the Netherlands—Belgium, Luxembourg, Germany—may be next in line.
Drivers should also be aware that using FSD may affect insurance policies. Some insurers have specific clauses regarding the use of Level 2 driver-assistance systems, and it is wise to confirm coverage before relying heavily on the feature. Additionally, the system’s Supervised status means you cannot legally or safely take your attention away from driving—doing so could lead to fines, license points, or worse.
Outlook: what to watch next
The coming weeks will be critical. Early adopters in the Netherlands will flood social media with video demonstrations and disengagement reports, offering the first real-world evidence of FSD v14.2.2.6’s competence outside North America. Those videos will shape public perception and, to some extent, the pace of further regulatory approvals. If the system handles Amsterdam’s notoriously complex traffic without major incidents, expect Tesla to accelerate expansion into other EU member states before the end of 2026. Conversely, a series of high-profile disengagements or accidents could trigger a regulatory clampdown and slower rollout.
Simultaneously, Tesla is almost certainly already preparing a 14.3 or 14.2.3 update that will incorporate lessons from these first few days of Dutch driving data. The company’s rapid iteration cycle means that today’s 2026.21.100 firmware might look primitive within a month. European owners should stay tuned to their car’s software tab; the era of supervised automated driving on European streets has officially begun.
