Tesla has released a new version of its Autopilot software that adds the ability to read speed limit signs, improving the accuracy of the speed limits displayed on the dashboard. The new version of the software also recognizes when a stoplight turns green. The car will notify the driver but won't start moving on its own.

Tesla first added the ability to spot stoplights and stop signs back in April. The initial version of the stoplight feature would slow down whether a traffic signal was red or green. The driver had to make the car proceed through the intersection if the light was green-otherwise, the car would stop.

The first version of Autopilot, which was based on technology from Mobileye, included the ability to recognize speed limit signs. But Tesla split with Mobileye in 2016 and began building more of its Autopilot technology in-house. As a result, prior to the latest software update, newer Tesla vehicles displayed speed limits based on a GPS-based database of roadway speed limits.
