- Tesla’s new "Child Left Alone Detection" feature, introduced in app version 4.44.0, aims to prevent heatstroke by detecting children or pets left in vehicles.
- It uses in-cabin 4D radar to identify subtle movements like heartbeats, sending alerts via the Tesla app or taking actions like activating HVAC.
- The feature is likely in testing, available in models like the refreshed Model Y, Model 3, and Cybertruck, with broader rollout expected in 2025.
- While promising, its effectiveness depends on radar accuracy and user response, and some older Tesla models may need hardware upgrades.
