A transportation vehicle system, for providing feedback to a user-worn wearable device, including a hardware-based processing unit and a hardware-based computer-readable storage device. The device includes a vehicle-function identification module that, when executed by the processing unit determines that a trigger condition has occurred. The vehicle-function identification module also determines, for responding to the trigger condition, a wearable-communication function including transmitting a vehicle signal to the wearable device. An activation module causes the processing unit to initiate transmitting the vehicle signal to the wearable device. The technology also in various embodiments includes the vehicle storage device, the wearable device, a storage unit of the wearable device, and processes including any of the operations disclosed herein.
