"Tesla's FSD v14 Lite is likely heading to a wide release for about 4 million older cars.
Ashok Elluswamy, Tesla's VP of AI, reviewed the latest build and said it is "likely going to wide release."
That would push the update to the roughly 4 million HW3 cars Tesla has built since 2019.
The upgrade uses AI distillation to teach the older HW3 computer how the newer HW4 V14 software drives, the first major FSD jump for those cars since early 2025.
Owners get new parking, unparking and reversing, plus smoother handling of merges, forks, traffic lights and pedestrians. It stays a supervised system, but it is the biggest step forward HW3 has seen in over a year.
