AP1 TESLA MODEL S AUTOPILOT 2021.4.18 SOFTWARE UPDATE | BUG FIXES ONLY

EV Channels Review

This video provides a practical test of Tesla's software update 2021.4.18 on a 2015 Model S equipped with AP1 hardware and an upgraded MCU2. The reviewer, Tesla Tom, focuses on bug fixes and performance improvements, noting that the update does not introduce new features like FSD visualization. During the test drive on Sydney roads, Autopilot generally performed well on open highways and during stop-and-go traffic, with the auto lane change feature being functional, albeit slow. A key observation was the system's ability to correctly read and adhere to school zone speed limits, dropping from 80 km/h to 40 km/h. The reviewer also discovered a new functionality on camera: the ability to match the current speed limit by flicking the stalk up once, a feature he previously believed was not available on AP1 Model S. Minor criticisms included the car sometimes hugging the right side of the lane too closely and a slightly abrupt braking action in one instance. The reviewer concludes that Autopilot remains effective on major roads and in traffic, emphasizing the importance of driver vigilance.
