Apple's new safety feature on iPhone and Apple Watch is Crash Detection which can detect if you've been in a car crash and will automatically call Emergency Services if you don't respond to the prompt.
This safety feature is very helpful if someone gets into a car crash and is unable to call for help but has suffered from severe injuries.
There's a new High g-force accelerometer sensor that can sense up to 256g's of extreme acceleration or deceleration to indicate if you've been in a car crash.
It is exclusively only available on the new iPhone 14 models and the new Apple Watch models.
