A study by the Brussels-based nonprofit Johanna found that Tesla’s Full Self-Driving (Supervised) system exceeded speed limits in 55% of tested 30 km/h zones. The vehicles averaged 44 km/h in these areas. Additionally, the system violated 20 km/h limits in 42% of residential shared streets and frequently failed to identify correct speed limits, often displaying 50 km/h instead of 30 km/h.
The findings were released ahead of an October 6 vote by the EU Technical Committee on Motor Vehicles regarding bloc-wide approval for FSD. Currently, the system holds provisional approval from the Dutch RDW, which has been recognized by Denmark, Belgium, Estonia, Lithuania, Slovenia, and Czechia. France, Sweden, Norway, and Finland have previously raised concerns regarding speeding.
Flemish Mobility Minister Annick De Ridder approved the system on June 10 following 5,000 km of supervised testing. The nonprofit has submitted its data to the Dutch RDW and the Flemish mobility ministry, requesting a review of these approvals. Tesla maintains that its vehicles do not speed excessively and align with the speed of surrounding traffic.
