Apple launched its iPhone 14 in September, and has since undergone a new test for its crash detection feature. Now, the test has revealed when the feature works and doesn't, and it has been found that it may not always be able to detect it. 

In a video from the Wall Street Journal, a demolition derby driver repeatedly rammed two distinct cars. He had a Google Pixel in the vehicle, which can also detect crashes, and an Apple Watch Ultra with an iPhone 14 model, reports AppleInsider.
