A YouTuber has quite literally crash-tested the iPhone 14’s Crash Detection feature and found Apple’s new emergency SOS function to reliably kick into action in the event of a controlled vehicle collision.

Serial gadget-smasher TechRax today published a video in which his team can be seen remotely controlling a driverless car containing an iPhone 14 Pro strapped to the headrest of the driver’s seat as they attempt to crash it into stationary vehicle.

After a series of near misses and the addition of several more decrepit road vehicles that form a wall to make for an easier target, the remotely controlled car successfully crashes at low speed in what could be described as a typical fender bender collision. After a short delay, the iPhone 14 Pro’s Crash Detection feature is automatically activated, and the phone initiates an emergency SOS countdown, which is then manually canceled by the team before it can call emergency services.

On the second successful attempt, the car hurtles into the wall of vehicles at a higher speed, its hood becoming concertinaed in the crash. Again, Apple’s Crash Detection feature is reliably activated and then manually canceled by the team.

While the results of TechRax’s tests don’t necessarily prove that the feature works as reliably in real-world, non-controlled, severe collisions, the fact that it did activate as expected should give confidence to iPhone 14 owners who keep the feature enabled.
