Tesla cars now detect speed limit signs

The vehicles' autopilot system warns of speed limits on the dashboard display and sends a notification if the car is still sitting in a green traffic light. The feature was released in the latest update to Tesla's "full self-driving" Autopilot. Tesla vehicles can already slow down at the red light and stop the signal.

In July 2019, Tesla's website advertised "full potential for autonomous driving", including automatic driving on the motorway - although it has always maintained that its autopilot is not built as an alternative to a human driver . Previous Tesla models have received the speed-limit mark, which was enabled by the firm's former business partner Mobileye.
Between 2013 and 2016, the Israeli manufacturer of camera sensors and software supplied the technology to Tesla for the autopilot feature used in its Model S and Model X vehicles. But in July 2016, the companies ended the relationship, citing the first reported autopilot fatality as a factor

Owners of cars manufactured under the partnership had complained that road signs were sometimes misunderstood. Tesla blog, Teslarty reported, vehicles did not register the speed limit mark at excessive speeds. Tesla's latest software update applies to autopilot cars manufactured after 2016, which are not fitted with Mobileye cameras.
Elsewhere, Cruise — a self-driving car start owned by General Motors — has said it uses artificial intelligence to train cars to understand the body language of bike users and pedestrians. It can be used to identify someone holding their hands up to a signal stop, or a cyclist may extend their left hand to indicate that they are turning left.
