Tesla has introduced some new safety features designed to stop drivers drifting out of their lane.
The two new additions - Lane Departure Avoidance and Emergency Lane Departure Avoidance - are designed with the goal of stopping common causes of accidents which can occur if a driver isn't using Autopilot.
The former will alert the driver if the car is exiting a lane without an indicator while hands aren't on the wheel.
If this happens too often while you're using cruise control, the car will automatically slow down to 15 miles below either the speed limit or your current speed - between 25 and 90 mph - with your hazard lights on.
Meanwhile, Emergency Lane Departure Avoidance automatically takes control of the car to steer it back into its lane if it thinks the vehicle is going to crash or veer off the road.
Although, like the other feature, this can be turned off, this one will be re-enabled at the start of the next drive.
