Telematics is a method of monitoring a vehicle. By combining a GPSsystem with on-board diagnostics it's possible to record – and map – exactlywhere a car is and how fast it's traveling, and cross reference that with how acar is behaving internally.
Who will use telematics?
All of us. The tech can be used for monitoring complete fleets of vehicles (everything from courier companies to emergency services) and even for tracking stolen cars. Increasingly it's going to be found integrated into 'connected' cars – think a situation where your cars breaks-down, and the AA is automatically alerted and sent data on your car's diagnostics – though the first wave will likely be car insurance firms desperate to offer 'usage based insurance' policies.
