The Belgian organization Johanna.be tested Tesla Full Self-Driving (Supervised) in Brussels and its surroundings. Over three days of testing, the car covered about 400 km, with a focus on zones with 20 and 30 km/h limits, streets for cyclists, and areas with heavy pedestrian traffic.

In 55% of the tested areas with a 30 km/h limit, FSD exceeded the set speed. The average speed in such sections was 44 km/h. At the same time, according to Johanna.be, the system often first recognized a 30 km/h road sign, but then displayed a 50 km/h limit on the car's screen.

A similar problem was found on streets with a 20 km/h limit: FSD exceeded the limit in 42% of the tested locations. In addition, testers recorded attempts to overtake cyclists on Belgian bicycle streets, where such a maneuver is prohibited.

However, the study was not entirely negative: Johanna.be noted that the car usually yielded to pedestrians and cyclists in advance. Tesla did not respond to Reuters' request for comment. A representative of the Flemish transport authority stated that the driver remains fully responsible for controlling the vehicle.

The results appeared on the eve of the expected October 6 vote by EU countries on the possible expansion of FSD approval to the entire European Union. The report has already been sent to the Dutch regulator RDW and the Flemish Ministry of Transport.
