Tesla Cuts Full Self-Driving’s Speed Margin From 50% to 10% Over the Limit in Europe

Tesla has cut the speed margin of its Full Self-Driving system in Europe from 50% above the posted limit to 10% above it. The change means European Teslas running FSD will now stay much closer to the legal speed limit than they did before — a significant tightening of how the system behaves on European roads.

The cut reflects the regulatory reality Tesla faces in Europe, where driver-assistance systems are governed by stricter UNECE rules than in the United States. European regulators have been scrutinizing how far assistance systems may exceed speed limits, and Tesla’s previous 50% margin was far more permissive than what the rules contemplate. The 10% margin brings FSD closer to how a careful human driver behaves — and closer to what European law allows.

For Tesla, the change is a reminder that FSD is not one product worldwide but a patchwork of regional behaviors shaped by local law. American owners still get the more permissive version, while European owners get a system that hews to the limit. As Tesla pushes toward unsupervised driving, these regional differences — not just the technology — will decide where robotaxis can actually operate.
