Tesla Update 2026.39.100 Quietly Reduces FSD/TAD Max Speed in Europe

The update’s release notes say only the name changed to Tesla Assisted Driving, but it also caps Speed Offset at 10% and resets it to 0% every drive.

Tesla’s latest software update in Europe does more than its release notes say. Update 2026.39.100, which includes FSD v14.2.2.6, renames FSD (Supervised) to Tesla Assisted Driving (TAD). “This change only updates the name of certain features and text in your vehicle, and does not change the way your features behave,” the release notes read.

However, that’s not the whole story. One of our readers, Addie, let us know that the update also lowers the maximum Speed Offset from +50% to +10% and resets it to 0% every time the car starts. Neither change is mentioned in the release notes, and several owners, including Addie, only noticed after installing the update.

What Changed

Speed Offset lets FSD drive above the posted speed limit by a set percentage. Before this update, European owners could set it as high as +50%. Now the limit is +10%, and the offset goes back to 0% each time you start a drive. That means you’ll need to set it again on every trip if you want FSD to go over the limit at all.

These are the same changes the Dutch RDW approved earlier this month, when it also notified the other EU countries that adopted its original approval framework to bring FSD to their roads. However, there was no announcement that the changes were already rolling out, and the release notes don’t mention them either.

Why Tesla Made the Change

The Speed Offset cap was one of the main changes several EU countries wanted. France and Sweden, along with road safety groups like the European Transport Safety Council, raised concerns about FSD being able to drive well over the speed limit. Germany later said it would back FSD in the upcoming vote for EU-wide approval if Tesla capped Speed Offset at 10% and renamed FSD to Tesla Assisted Driving.

With both changes now live, Tesla has met Germany’s two main requests ahead of December’s vote on bloc-wide approval. Regulators have said more changes are expected before then, mostly aimed at keeping drivers alert. Hopefully, Tesla’s future release notes will explain those changes more clearly so owners know what they’re installing.
