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, or TAD, Not a Tesla App reported.

"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. That is not the whole story. A reader, Addie, told the site that the update also lowers the maximum Speed Offset from +50 percent to +10 percent and resets it to 0 percent every time the car starts. Neither change is mentioned in the release notes, and several owners, including Addie, only noticed after installing the update.

The same changes Dutch regulators approved

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 percent. Now the limit is +10 percent, and the offset goes back to 0 percent at the start of each drive, so drivers have to set it again on every trip if they want the system 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. There was no announcement that the changes were already rolling out, and the release notes do not mention them, Not a Tesla App reported.

Germany's conditions, ahead of a December vote

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 percent and renamed FSD to Tesla Assisted Driving, the site reported.

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. Not a Tesla App reviewed the release notes and said they mention the name change but not the Speed Offset cap or the reset at the start of each drive. For owners, the practical change is immediate: a tighter cap, a reset at every start, and a new name that presents the system as assisted driving — even if the notes said behavior would not change.
