Tesla has started using new parameters such as wind direction, air density and humidity to improve the accuracy of range predictions, according to the American automotive news site Electrek. Citing a tweet from a well-known hacker named “Green”, the report said the new mileage calculation method may only be trialled in China for now, with a wider rollout later.
Travel energy calculations now take into account crosswinds/headwinds, air density and humidity (probably only in China for now?), Green tweeted on Wednesday. Tesla Trying To Calculate Range More Accurately By Including Wind, Air Density And Other Factors:
The interior cabin radar finally starts to get signs of life so might come live relatively soon? (on s/x cars)
Trip energy accounting now takes into account cross/headwinds, air density and humidity when available (possibly China only for now?)

Citing a software release note, Electrek also said that Tesla has also begun preparing to roll out a new software update (likely on August 2), including better-charging calculations and other tweaks. In 2018, the Musk-led company added more features to estimate range, including using altitude and temperature data in calculations.
Tesla drivers can enter their destination into the car’s interactive system to determine if they have enough power to complete the trip. These estimates may vary slightly due to external factors such as weather. The new feature could improve the accuracy of mileage predictions by several percentage points.
