Waze is mostly meant to help you avoid traffic snarls and speed traps, but it's now performing a valuable public service. Effective immediately, the navigation app will notify you about AMBER Alerts for abducted children wherever you're driving. Stop for at least 10 seconds and you'll get details for both the victims and any vehicles they might be traveling in. It's a simple upgrade, but it could make all the difference if you spot a child or captor in time for police to stage a rescue.
