So I currently use a combination of Launch Center Pro and Workflow (the developer of which was purchased by Apple last year, and appears to be the source of what has now become Siri Shortcuts) to do what you're describing. I have a Workflow that when run, uses Maps to estimate the drive time between wherever I am and my house, pads the estimate by 5 minutes, then adds that to the current time to get an ETA, formats it into a text message and sends the ETA to my wife. In Launch Center Pro, I have a geo-fenced shortcut that presents a notification to run my workflow whenever it sees that I have left the area around my office building. The UX is, halfway between my office building and my car, I get a notification from LCP - I tap the notification, Workflow thinks for a minute, and presents me with a text message to my wife and I tap "send". As nice as this is already, I believe Siri Shortcuts may improve it in several ways: 1) Currently, apps are not allowed to send messages without explicit user interaction, so Workflow can't actually text my wife, it just presents me with an imessage screen and an already-written message that I must tap "send" on 2) Workflow does not support geofenced or time-based running of workflows, hence why I need LCP to launch my Workflow based on a geofence. If Siri Shortcuts supports this, then I won't have to rely on LCP anymore. 3) There is no way (that I'm aware of) to trigger my workflow automatically, I must tap a notification and unlock my phone, or run an app and select the workflow within it. An improvement would be a programmable Siri Shortcut ("Hey Siri, let my wife know my ETA"), and even better would be automatic running of workflows based on defined conditions, so my workflow would run and send a message automatically when crossing the geofence without me even needing to be aware of it (besides maybe a notification that lets me know the workflow has run).
