iPhones calling 911 from owners’ pockets on rollercoasters

New iPhones which can detect car crashes and notify emergency services appear confused by thrill rides

Apple's newest phone has been automatically calling emergency services from the pockets of people riding rollercoasters in the US, mistaking the bumps and jerks of the rides as car crashes.

The latest iPhone 14, as well as newer Apple watches, includes a feature that detects the signs and vibrations typical of a serious car accident - and calls 911 if the owner does not respond to a prompt to cancel.
