A Belgian road-safety group reports that Tesla’s supervised self-driving system (often referred to as FSD) frequently misreads posted speed limits during real-world driving tests in Belgium. The group says this leads the system to set speeds inconsistent with what road signs indicate.

The two reports both describe the same core finding: speed-limit recognition errors appear to be a recurring issue in the tests. One outlet emphasizes the context of Belgium’s specific driving environment and the safety implications of interpreting signage incorrectly, while the other highlights that the system’s supervised approach does not prevent these misreads.

Neither report, based on the provided excerpts, indicates that the safety group attributes the issue to a single cause such as a software update, map data, or a particular sign type. They also do not specify whether Tesla disputes the findings or provides an immediate technical explanation in the excerpts. Overall, the reports center on the accuracy of speed-limit detection as a risk area during assisted driving in Belgium.
