Tesla has started rolling out its 2023.38.4 software update, introducing a range of new features aimed at enhancing safety, convenience, and entertainment for owners of Model S, Model 3, Model X, and Model Y vehicles. The update includes a "Faster Hazard Lights After a Crash" feature, designed to make hazard lights flash more rapidly following a collision to increase visibility. This feature is not applicable to all types of vehicle incidents, according to the 2023.38.4 release notes shared by Tesla Software Updates. Another notable addition is the "Predictive Charger Availability" feature. Superchargers will now forecast availability and wait times by considering the travel time for Tesla vehicles en route and past activity at the charging station. The update also brings a minor adjustment to windows during software updates. The windows will minimally adjust to allow doors to open and close more easily and will return to their original position after the update is complete.
