This is a huge improvement, but one other manufacturers have had for a while.
To help Tesla stay ahead of the competition, the company's semi-autonomous Autopilot technology is constantly evolving thanks to over-the-air software updates adding new features such as automatic lane changing and the ability to stop for red lights and stop signs.
As part of a new update available for the Model 3, Model S, Model X, and Model Y, Tesla's Autopilot can now utilize the car's cameras to detect speed limit signs to "improve the accuracy of speed limit data on local roads." If a speed limit sign is detected, it will be displayed in the driving visualization. This isn't new tech, as a number of manufacturers have done this before, but it is a first for Tesla.
This data will then be used to set speed limit warnings to help you avoid getting a speeding ticket. Previously, Tesla's Speed Assist system relied on GPS data to detect the road's speed limit. This has been a long-requested update as owners have complained Tesla's speed limit detection has been inaccurate.
Other improvements added in the update include a chime that plays when a traffic light you're waiting for turns green. If the Tesla is stopped behind another car, the chime will play when the car drives off unless Traffic-Aware Cruise Control or Autosteer is active.
The driving visualization can now also display additional objects such as include stop lights and select road markings and show how the suspension system dynamically adjusts the damping of each wheel according to the road conditions.
Autopilot can now detect if the driver is about to run a stop sign or red light while Autosteer is in use, but it will not stop the car so the driver still needs to be attentive. Lastly, the Traffic-Aware Cruise Control or Autosteer speed can be set to the current speed by tapping the cluster speedometer. Drivers can still tap the speed limit sign to adjust the set speed to the speed limit.
