Tesla extends FSD tech to older HW3 cars with 'Lite' update
Tesla has begun rolling out FSD v14 Lite to Hardware 3 cars (AI3), a supervised Level 2 update that distills HW4’s v14 guidance into the HW3 stack to improve city navigation, safety, and added parking/reversing features. The rollout starts with early-access drivers, with a wider release expected in the coming weeks; unsupervised autonomy remains unavailable on HW3, and the update does not fulfill the original promise of full self-driving.
