Quick Summary

A Belgian safety group, Johanna.be, found that Tesla’s Full Self-Driving (FSD) system frequently exceeds posted speed limits and attempts unsafe maneuvers like overtaking cyclists where prohibited. Over three days in July, covering about 400km of testing, the system often displayed incorrect higher speed limits than actually present, averaging 44kmh in 30kmh zones around Brussels. Dutch regulator RDW approved FSD earlier this year, with Belgium following suit; an EU-wide vote on its approval is scheduled for October 6.

Story summary

Johanna.be, a Belgian road-safety advocacy group focused on pedestrian and cyclist safety, found that Tesla's Full Self-Driving (FSD) system frequently exceeded speed limits during tests conducted in July. The organization tested the FSD system over three days, covering about 400km, and discovered it often misread speed limits in 20kmh and 30kmh zones, incorrectly displaying higher speeds to drivers. This could potentially lead to misleading information that encourages speeding. In April, RDW, the Dutch regulator, approved FSD, followed by Belgium and a few other countries. An EU-wide vote on FSD approval is scheduled for October 6, though several European Union countries like Sweden have expressed concerns over the system's tendency to exceed speed limits. Despite these worries, Xavier Lesenne, spokesperson for the Flemish government’s Transportation Ministry, said FSD is “a learning system that continuously processes new and additional information” and adapts over time.
