A regulatory letter shows that Sweden's traffic authority recommends voting against Tesla's European-wide promotion of its FSD supervisory version unless Tesla disables the software's speeding function. The Swedish Transport Agency (TRV) said in a previously unpublished letter dated April 30 that Tesla should not be approved for use on EU roads unless its "FSD (supervisory version)" function removes its ability to ignore speed limits.

The letter has been sent to the EU Technical Committee on Motor Vehicles (TCMV). The committee will meet again on June 30 to discuss the matter, before voting on whether the technology should be rolled out across the EU.

Tesla has received approval in some European countries for its FSD system, which allows vehicles to drive autonomously on city streets and highways under human supervision. If it can get EU-wide approval, it will help Tesla's sales in the region.

Tesla's owner's manual states that drivers should not rely solely on the system to determine the speed limit, but must "drive at a safe speed based on traffic and road conditions."

However, FSD allows the user to set a "speed offset" that causes the vehicle to exceed the speed limit within a range set by the driver.

"Allowing automated driving systems to systematically exceed legal speed limits... could undermine the legal framework and the expected safety benefits of vehicle automation," the Swedish Transport Agency (TRV) said in the letter.

The agency called on Tesla to remove the feature. "If it cannot be removed, the Swedish Transport Agency recommends that the European Technical Committee on Motor Vehicles (TCMV) vote against the introduction of FSD."

A TRV spokesman said its position had not changed since the April letter and that it was in agreement with ST.

"It is my understanding that Sweden's representatives at TCMV will only vote in favor if Tesla's overdrive feature is removed," the spokesperson said.
