My car does not have Bluetooth, so I have a USB plug-in iBeacon in the car that uses Pushcut, some Shortcuts and Data Jar (beta) to set up my phone for the drive (DND on, Apple Maps with destination, entertainment: Overcast, Audible (only opens the app, I have to press play!), Apple Music). At the end of the trip, the same persistent notification from Pushcut can stop the audio and turn off DND.
Another option is when “leaving” the iBeacon that it can fire the end of journey notification, which also allows me to save my car’s location, some notes and a photo to Data Jar so that I can use that information and fire off Apple Maps to locate it later.
Everything could be done just using more menu options in Shorcuts or Pushcut, but Data Jar allows me to record if I am the start or end of a journey so Shortcuts can figure out whether to fire things up, or turn them off.
I’m just playing around with ideas for the moment and refining the options. It’s all rather rough, but I like the basics.
