Tesla is officially discontinuing the option to purchase its Full Self-Driving software as a permanent, upfront add-on, transitioning exclusively to a monthly subscription model. This strategic pivot effectively ends CEO Elon Musk’s long-standing claim that the technology would serve as an appreciating asset for vehicle owners. By shifting to a recurring service fee, the company reduces its legal liability regarding past promises of achieving total vehicle autonomy. The decision also reflects market pressures, as high upfront costs and increasing competition from other automakers have led to a decline in customer adoption. Ultimately, this change redefines the software as a temporary driver-assist utility rather than a one-time investment in a future robotaxi.
