I just purchased my first 2019 Tesla Model 3 Standard Range. I absolutely love the car! By far the best car i have ever owned. I'm learning more and more as i drive it. I'm educating myself about the Autosteer function and do not see it inside Autopilot. Is Autosteer included and free with all Teslas? I do see an upgrade option that has Autosteer included but it is $3000.00. Can someone help shed some light on this?
