The launch of Tesla's Supervised Full Self-Driving (FSD) in Europe has entered its final phase. Analysis of the latest internal build, Tesla 2026.4.1, reveals that the system now includes a European Regional Expansion module and a new production switch called is_supervised_active_eu, which directly controls activation in the EU. This is no longer a hidden feature but a ready-to-use activation mechanism integrated into the main development branch.

At the same time, Tesla has uploaded new user manuals for the Netherlands and France. These aren't just translations of North American instructions but adapted behavior schemes for situations typical in Europe—such as navigating complex roundabouts and driving near trams. This level of localization indicates that advanced testing stages have been completed.

The Netherlands serves as the certification hub: here, Tesla is conducting official demonstrations of version 14.1.7 to meet UN-R-171 requirements, including the operation of the full end-to-end architecture. RDW remains the final regulator that must grant approval. If critical issues are found during inspections, activation could be postponed to the next build, such as 2026.4.2.

Nevertheless, the inclusion of the European module in the current main development branch is a strong indicator that the company is preparing for a large-scale release, not just an experimental option. The built-in logic for interacting with trams and roundabouts further suggests that the technical aspects have reached production-level maturity.

For readers, the main intrigue of the FSD launch in Europe lies not so much in the system's activation itself, but in the transition from the American testing model to the European regulatory framework. This shift will test the maturity of Tesla's algorithms, as the EU demands a high level of predictability and reproducibility in vehicle behavior.
