Tesla is adding a redesigned self-driving app that lets eligible owners subscribe to Full Self-Driving in one tap and review how often they use it. The display includes a usage bar chart and streaks counting consecutive days with FSD engaged. Access requires Tesla's A14 chip, also called FSD Hardware 4.0, which began shipping in January 2023. The supervised system can steer, change lanes and park, yet drivers must remain attentive because the vehicles are not autonomous. A subscription costs $99 a month. Tesla also has a corporate incentive to expand adoption. Reaching 10 million active FSD subscriptions by 2035 is one product target tied to Elon Musk's compensation package.

A streak converts supervised driving into a habit that can be won, maintained and broken. Consumer apps use such counters to pull a person back toward language lessons, exercise or shopping. Inside a car, the same device meets an activity where divided attention carries physical consequences. The interface rewards activation frequency while the product instructions assign continuing responsibility to the driver. That pairing produces an awkward behavioral contract. Tesla benefits when owners subscribe and engage the software repeatedly. Each owner must still watch the road and intervene. Statistics can also change the meaning of a trip. A commute becomes evidence of loyalty to a feature, and an unused day becomes a gap in a sequence. The concrete reward is a longer number on the dashboard, earned while the driver keeps both hands ready for the wheel.
