Be aware that with Single Pull, when Autopilot Features is set to Autosteer (Beta), you'll bypass Traffic-Aware Cruise Control. Similarly when Autopilot Features is set to Full Self-Driving (Beta), you'll bypass Autosteer (Beta) and Traffic-Aware Cruise Control.

With Single Pull, when you cancel Autosteer (Beta) or Full Self-Driving (Beta), whether you take over the steering or push up the stalk one time - you'll immediately return to manual driving.

As with all Autopilot features, you must continue to pay attention and be ready to take immediate action including canceling the feature and returning to manual driving.
