FSD (Full Self Driving) is a one time purchase or subscription option for Tesla Model S, 3, X, CT, and Y.  It provides features like Smart Summon, the ability for the car to drive from on ramp to offramp via autopilot (a feature known as Navigate on Autopilot) and now the ability to navigate on city and rural roads with or without lane markings. The software recongnixes stop lights, stop signs, speed limit signs, and handles left and right turns with changing lanes as needed. More info can be found here.

FSD is currently level 2 autonomy...ie the driver still has to pay attention to the cars driving and take over if necessary.  There are plenty of youtube videos of FSD drives. I will put examples of drives I find interesting here.

Version 12

FSD Beta v12 upgrades the city streets’ driving stack to a single end-to-end neural network trained on millions of video clips, replacing over 300k lines of explicit C++ code. This major rewrite basically gets rid of code like "here is a stop sign ahead, this is what to check for and this is what you do in various situations" and instead depends on the AI engine being trained by watching video clips of what good drivers do when they see such signs. Here are some first user videos of driving with version 12:
