This feature would allow one to self identify as a slow moving object updating one's position as necessary (every .2 miles?), alerting approaching vehicles. This would allow a runner or a horse rider or road working crew to alert drivers to be alert as the approach. Perhaps with "hazard" lights on the main screen so the user knows they activated this feature. The feature would self disable above 25 mph. And perhaps reactivate below 25 mph unless disabled.
