Back Off Radio.

Tailgating is a common and dangerous habit on Dubai's roads, and drivers ignore conventional warnings.

Sensors on the front and rear of Dubai taxis switched on above 60 kph. If a taxi drove too close to the car ahead, a safety message played through its own speakers. If a car tailgated the taxi, a message was sent to that car's radio, as long as it was tuned to an ARN network station. Messages ran in English, Arabic, Hindi and Urdu.
