At the time it was launched, Autopilot 2.0 vehicles with HW2 actually had fewer features than HW1 vehicles for example, HW2 vehicles were unable to be summoned in 2016. In October 2016, Autopilot sensors and computing hardware transitioned to hardware version 2 (HW2) for new cars, the upgraded hardware collectively was called Autopilot 2.0 to distinguish it from the original Autopilot/HW1 vehicles. By November 2016, Autopilot had operated for 300 million miles (500 million km). In November 2016, Autopilot 8.0 was updated to encourage drivers to grip the steering wheel. Version 8.0 processed radar signals to create a point cloud similar to lidar to help navigate in low visibility. Version 7.1 removed some features to discourage risky driving. The first Autopilot software release came in October 2015 as part of Tesla software version 7.0. Tesla cars manufactured after September 2014 had the initial hardware ( hardware version 1 or HW1) that supported Autopilot. Initial versions were built in partnership with Mobileye, but Mobileye ended the partnership in July 2016 because Tesla 'was pushing the envelope in terms of safety'. In October 2014, Tesla offered customers the ability to pre-purchase Autopilot that was not designed for self-driving.

FSD beta testing started in October 2020.

At the same time that EA was introduced, Tesla also offered Full Self-Driving ( FSD) as an upgrade option to EA in 2016, which would extend machine-guided driving capabilities to local roads. Enhanced Autopilot ( EA) was announced later in 2016 as an extra-cost option that used a new hardware suite developed by Tesla the key distinguishing feature for EA, 'Navigate on Autopilot', which uses the new hardware suite to guide the vehicle on controlled-access roads, from on-ramp to off-ramp, was delayed until 2018. By 2016, the Mobileye-based Autopilot had added automatic emergency braking, adaptive cruise control, and lane centering capabilities when Tesla and Mobileye dissolved their partnership that July. Autopilot, as initially introduced in 2014, referred to automatic parking and low-speed summoning on private property, using sensor and computing hardware developed by Mobileye. Elon Musk first discussed the Tesla Autopilot system publicly in 2013, noting that 'Autopilot is a good thing to have in planes, and we should have it in cars.' Over the ensuing decade, Autopilot went through a series of hardware and software enhancements, gradually approaching the goal of full autonomy, which, as of January 2023, remains a work in progress.
