Notifications for Vehicle Alarm

Suggestion: have a feature that would generate enhanced notifications via automated voice telephone calling and/or persistent notifications if the vehicle alarm goes off.  

Background:  Many times our phones today "alert" with social media chimes and other non-essential information and we naturally don't immediate take notice .  Having a voice notification, similar to how many home alarm systems work today, would call immediate attention to the situation.  Another method would be to create a persistent notification to a smartphone that would continue until the user acknowledges or a predefined time period.
