"Tesla is expanding its Full Self-Driving (FSD) capabilities to millions of older vehicle models, despite lacking the latest hardware. In a move that could significantly boost the company's autonomous driving ambitions, Tesla is rolling out a 'FSD Light' feature to approximately four million vehicles produced prior to 2021. This development comes as the electric vehicle manufacturer continues to push the boundaries of autonomous driving technology, with many of its newer models already equipped with advanced hardware designed specifically for FSD. However, the implementation of FSD Light on older models raises questions about the potential trade-offs between safety and functionality."
