Feature: a virtual board leash using Bluetooth to kill/stop the board when out of range.

Use case: to allow for strangers to test the board without fear of them stealing it. To allow kids to ride and not go miles away.

Implementation: through the app, alternatively an accessory that would work like car key.

Bonus: a tester/kid mode that keeps the board from going super fast. Similar to a valet mode in a car.

They could be implemented completely with software in app, when the board goes out of range dies/full pushback. Once that occurs, the bird requires authorisation before it will move again, back into valet mode, or regular mode.
