Tesla Software Update Improves Speed Limit Sign Detection

Tesla’s latest software update (2020.40.0.4) includes a few new features and an improvement to its Speed Assist feature.

The update rolled out to Tesla owners on Wednesday. In addition to improvements to “Speed Assist,” which debuted in August, the update also included new security and infotainment features.

Notable additions to the software include:

Speed Assist Improvements – “In addition to local roads, Speed Assist now leverages your car’s cameras to detect speed limit signs to improve the accuracy of speed limit data for highways.”

Priority Bluetooth Device – “To avoid connecting to the wrong nearby phone, you can now set your priority Bluetooth device. Your car will attempt to connect to the priority device associated with the profile selected before it attempts to connect to other paired phones.”

Glovebox PIN – “Protect the valuables in your glovebox with a 4-digit PIN.” 

Charge Port Inlet Heater – “Your car can now use the charge port inlet heater to help defrost the inside of the charge port. The charge port inlet heater can be activated in cold ambient temperatures by enabling preconditioning using the mobile app, activating the rear defrost button on the vehicle’s touchscreen, or preconditioning the vehicle using scheduled departure.”
