Apparently the software genii at Apple have come up with something called “crash detection" for iPhones and Apple Watches. According to the Tame Apple Press this is not a much needed function for when its software breaks, but a wonderful thing which uses data from device sensors to tell if users are in a car crash.

Basically the software uses the accelerometer to detect car accidents as they occur, by measuring a sudden spike in gravity, or "g" forces on impact.

Apple introduced a fall-detection feature in its smartwatch several years ago that senses when wearers have taken a hard fall and dials 911 if they don't respond to a notification asking if they are OK.

The company this year added a feature to the newest version of its iPhone operating system that assesses the walking steadiness of users. The timing of the new feature could change, or Apple could choose not to release it, people familiar with the company's development process said.

Apple has been testing the crash-detection feature in the past year by collecting data shared anonymously from iPhone and Apple Watch users. The outfit claims it has already detected more than 10 million suspected vehicle impacts, of which more than 50,000 included a call to 911.

Apple has been using the 911 call data to improve the accuracy of its crash-detection algorithm, since an emergency call associated with a suspected impact gives Apple more confidence that it is indeed a car crash, according to the documents. The documents don't specify how Apple users are sharing information with the company so it can test its new crash-detection algorithm, but as it is Apple you don’t need to worry about it sharing information with your insurance company.

The company also did not say how much of the emergency services’ time was wasted on false positives, because we all know that Apple software never makes mistakes particularly if users hold it the right way.
