You may still not want to trust the feature. Some early adopters warned that the Autopilot does not always recognize cones, potentially leading to dangerous changes in the lane – say, directing you to cross-traffic or construction. Tesla reminded drivers that "they have to pay attention at all times," so he knows it's not a substitute for keeping your eyes open.
This is still an important step for Tesla. He still intends to enable self-driving in the future, and this will require cars that can recognize and handle almost any road object. At first glance, a small update like this can go a long way toward true hands-free management.
