The iPhone 14’s new Crash Detection feature, which is supposed to alert authorities when it detects you’ve been in a car accident, has an unexpected side effect: it dials 911 on rollercoasters.

According to a report from The Wall Street Journal, the feature has had law enforcement sent to amusement parks on numerous occasions after mistaking a thrill ride’s twists, turns, and hard braking for a real emergency.

When it calls law enforcement, it will play an audio message that alerts authorities you’ve been in a crash, and also provides them with your location.
