Release Notes

Adjacent Lane Speeds

This only is available currently for vehicles in the United States.

When your vehicle is moving at a significantly faster speed than vehicles in neighboring lanes, Autopilot now automatically reduces your driving speed. This is helpful in heavy traffic situations or when there is a long line of vehicles merging into a different lane or exiting onto an off-ramp. When your vehicle detects that adjacent lane traffic is significantly slower, the lane is highlighted with arrows and its vehicles are highlighted gray in the driving visualization. This speed adjustment can be temporarily overridden by pressing the accelerator pedal.

Automatic Wiper Improvements

Automatic wipers have been improved to be more likely to activate when it is lightly raining and respond to changes in rain intensity for more environments. The automatic wipers are now employing the first production deep neural network trained with over 1 million images for the detection of water dropIets on a windshield and additional weather cues. If automatic wipers is not performing to your preference, any manual adjustment to wiper speed will be captured to further train and improve the network in future software updates.

To enable automatic wipers, tap the windshield wiper icon located in the "Cards" area on the touchscreen and select AUTO.

Automatic Lane Change Improvements

Automatic lane changes have been tuned to make lane changes with more confidence. When the adjacent lane is detected to be open, automatic lane changes will initiate faster and be more assertive.

Autosteer Stop Sign Warning

Your car may warn you in some cases if it detects you are about to run a stop sign, in addition to stop lights, while Autosteer is in use. This is not a substitute for an attentive driver and will not stop the car.

This release contains minor improvements and bug fixes.
