TESLA READ SPEED SIGNS | TESLA SOFTWARE UPDATE 2020.40.4 | MODEL 3

EV Channels Review

Tesla Tom evaluates the new speed sign recognition feature in Tesla Software Update 2020.40.4 for the Model 3 Performance Stealth in Australia. The update also introduces priority Bluetooth device selection and a glovebox PIN. Tom's testing reveals that traditional speed limit signs are generally recognized well, with the car accurately adjusting speed, especially when dropping limits. However, the system struggles with electronic speed signs on gantries and some roadside displays, a significant drawback for freeway driving. The reviewer notes that the car sometimes hesitates to increase speed to the posted limit but reliably decreases it. Edge cases like dual speed limits (30/60) are handled by defaulting to the lower limit, and school zone signs are mostly recognized. The glovebox PIN and Bluetooth prioritization are deemed useful additions. Overall, the speed sign recognition is a promising but incomplete feature, particularly needing improvement for electronic signs.
