Belgium Test: Tesla FSD Frequently Exceeds Speed Limits, Putting Pressure on EU Approval
nashnova research
A Belgian road-safety group found that Tesla's FSD averaged 44 km/h in 30 km/h zones — and kept displaying the wrong speed limit even after recognizing the correct sign. With an EU-wide approval vote possible on October 6, the report is the most concrete ammunition opponents have.
What was tested — and how bad are the results?
Belgian road-safety group Johanna.be ran a three-day, ~400 km real-world test in July.
Key finding: across most 30 km/h zones around Brussels, FSD averaged 44 km/h — nearly 50% over the limit.
The stranger detail: the car's screen showed it had recognized the 30 km/h sign, yet the dashboard kept displaying 50 km/h as the speed ceiling. This means → the system "saw" the sign but fed the driver a higher, incorrect reference speed.
In plain terms = imagine a passenger repeatedly telling you "the limit here is 50" while the roadside sign says 30 — you'd struggle not to follow the voice in the car.
Where does EU approval stand?
The Netherlands' vehicle authority (RDW) approved FSD in April; Belgium and several other European countries followed.
An EU-wide vote could take place on October 6, deciding whether FSD can operate legally across the bloc.
Johanna.be has submitted its report to Belgium's Flemish transport department and the Dutch RDW, demanding they reassess their approval decisions.
This means → the report's timing is deliberate — landing just before the bloc-wide vote to create real friction in the approval process.
How do supporters respond?
Flemish transport spokesman Xavier Lesenne called FSD "a continuously learning system" and said the driver bears "100% responsibility" and must be ready to take over at any time.
He cited Tesla data showing the technology has "significant potential" in accident prevention.
Tesla's own study published this month claimed FSD vehicles do not excessively speed and travel at speeds consistent with surrounding traffic.
In plain terms = the supporters' core logic is: the system is imperfect, but liability sits with the human, and on balance it makes driving safer.
Did FSD get anything right?
The report acknowledged positives: FSD was "cautious and courteous" around pedestrians and cyclists, often yielding proactively.
But the conclusion was that these strengths "do not offset" the documented violations on speed limits and bike-lane rules.
This reflects a deeper debate — should autonomous systems be judged on overall safety outcomes, or on compliance with every individual traffic rule? The EU's October 6 vote will be the first formal answer to that question.
