Can I trigger trip recording when I disconnect from home Wi-Fi?

When your iPhone leaves home Wi-Fi range, that's almost always because you're walking or driving away. You can use that as a trigger. In the Shortcuts app: Automation → + → Wi-Fi → choose your home network → "Is Disconnected" → add Speedometer's "Start or Resume". Create the reverse — Wi-Fi → home network → "Is Connected" → "Stop Trip" — to end the trip when you get home. Useful for cyclists, runners, and walkers who don't have car Bluetooth. Combine with Driving Focus for higher accuracy.
