Tesla’s European FSD Safety Claim: What the 4.1× Figure Really Shows

Tesla’s September 1, 2026 publication of its “Article 39 – FSD (Supervised) Dashboard” was designed to support a wider European rollout of its supervised driver-assistance system. Its headline claim was that vehicles using FSD had 4.1 times fewer collisions than manually driven Teslas across more than 100 million kilometres of public-road driving in the Netherlands, Denmark, Belgium, Estonia and Lithuania. Tesla said the data covered driving between April and August and included three collisions on highways and nine on other roads. 115

That is a notable company-reported result—but it should be read as a claim about a selected comparison, not as a definitive safety verdict. FSD (Supervised) still requires an attentive human driver, and the dashboard does not establish that the system is fully autonomous. 914

What Tesla’s 4.1× claim means

Tesla compared collision rates for Teslas operating with FSD (Supervised) against rates for manually driven Teslas, adjusted for distance travelled. The company presented the dashboard as a broader safety case covering collision rates, regional safety indicators, lane changes, engineering-fleet validation and fixed-route testing in six European cities. 9

Tesla also said FSD was being used by more than 70,000 customers in the five countries and was accumulating more than 1 million kilometres per day. 215

The result is relevant to Tesla’s regulatory argument because it suggests that supervised automation may reduce some types of collision exposure compared with manual driving in the environments where the system was operating. But the result does not answer every safety question regulators would need to consider, including how the system performs across different road designs, weather conditions, traffic patterns, driver behaviours and collision severities.

Why the dataset cannot be treated as an independent safety benchmark

The most important limitation is provenance: Tesla selected, analysed and published the evidence. The comparison is also between FSD-equipped Teslas and manually driven Teslas, rather than between randomly assigned vehicles under equivalent conditions. Differences in driver population, routes, trip types, roads, weather, vehicle use and supervision could affect the result.

The public material, as described in the supplied reporting, does not provide enough underlying information for outsiders to fully reproduce the headline comparison or assess every potential source of bias. It does not by itself provide a complete independent account of exposure, route mix, driver interventions, weather, vehicle configuration or crash severity. 17

That caution matters because Reuters previously reported that some of Tesla’s broader safety comparisons relied on invalid or mismatched benchmarks that could exaggerate the apparent advantage of its technology.

The dashboard therefore provides evidence that Tesla wants regulators to consider. It does not, on its own, prove that FSD is safer in every circumstance or that it can safely operate without human supervision.

The advertised advantage narrowed from 5.2× to 4.1×

Tesla had previously publicized a comparison claiming 5.2 times fewer collisions across the same broad group of European countries. A later figure of 4.1 times fewer collisions represents a smaller relative advantage as the reported mileage base expanded. 1

That change should not be overstated. The two figures came from different measurement windows and may not use identical exposure mixes or definitions. A lower relative advantage does not necessarily mean that FSD’s absolute collision rate worsened. It does mean that Tesla’s published comparison became less favourable over time, and the available material does not establish why.

The sensible conclusion is limited: Tesla’s data continued to show a company-reported advantage, but the size of that advantage was not stable across the published periods.

Why the dashboard mattered for EU approval

Tesla released the dashboard as Europe considered whether to broaden recognition of the Netherlands’ provisional approval. The Dutch vehicle authority RDW granted that approval under Article 39 of Regulation (EU) 2018/858, an exemption route for technologies that do not fit fully within harmonised EU rules. The regulatory path also involved UN Regulation No. 171, which covers driver-control assistance systems. 1050

Tesla said it had adjusted FSD to comply with the existing regulatory framework while seeking targeted exemptions for behaviours that did not fit the rules. The published dashboard was presented as one of the key pieces of evidence supporting the Dutch approval. 4915

The European Technical Committee on Motor Vehicles was expected to vote on October 6, 2026, on whether to extend the approval across the EU. 250

Which countries recognized the Dutch approval?

The five countries identified as recognizing the Dutch RDW approval were:

• The Netherlands
• Denmark
• Belgium
• Estonia
• Lithuania

Tesla said more than 70,000 customers were using FSD in those countries. 215 A tracker cited in the supplied material estimated that the five-country group represented about 8.9% of the EU population, though that percentage is an estimate from the tracker rather than an official figure in the regulatory sources. 8

Why transparency became a central objection

The safety dashboard did not make the entire regulatory record public. Reuters reported that the Dutch regulator RDW would not release details of its safety testing or explain publicly why it concluded that FSD was safe, with Tesla and regulators citing trade-secret concerns. Safety experts disputed whether that level of secrecy was appropriate for a system whose approval could be extended across the EU.

Reuters also reported that emails showed Tesla had pressed European officials to keep the safety review confidential. That created a transparency problem: regulators considering EU-wide recognition would be evaluating a public, company-selected dashboard while much of the underlying approval file remained unavailable for independent scrutiny.

The European Transport Safety Council called for independently verifiable evidence and answers to unresolved safety questions before countries recognized the provisional approval. The supplied source material indicates that France opposed the authorization, but it does not provide enough of France’s formal reasoning to state its objections in detail without overstating the record.

How the release intersected with Tesla’s U.S. legal fight

The European publication also came as Tesla challenged class certification in a U.S. consumer case alleging that the company misled buyers about the capabilities of its self-driving technology. Tesla asked the Ninth Circuit to decertify the class, arguing that there was no proof all class members had seen the same allegedly misleading statement.

A Ninth Circuit panel appeared divided during oral arguments, according to Bloomberg Law. The appeal concerns whether the case can proceed as a class action; it is not a final finding that Tesla is liable for deceptive marketing.

That legal context does not determine whether the European safety data is accurate. It does, however, explain why claims about what FSD can do—and how those claims are supported—were under scrutiny on both sides of the Atlantic at the time Tesla released the dashboard.

Bottom line

Tesla’s dashboard made a clear regulatory case: across more than 100 million kilometres in five European countries, the company said supervised FSD had 4.1 times fewer collisions than manually driven Teslas. 115

The strongest caveat is equally clear: the comparison was produced by Tesla, used a non-randomized manual-driving benchmark and was published without the full underlying regulatory evidence needed for independent replication. The reported advantage also narrowed from an earlier 5.2× figure as the mileage base grew.

For the October EU decision, the dashboard is therefore best understood as supporting evidence for Tesla’s application—not as a conclusive answer to whether FSD (Supervised) is safe across Europe’s full range of roads and driving conditions.
