We have an in car digital coaching service for at risk young drivers. When they drive in a risky way it beeps and reports the time place date and manner to their personalised web console. They can see if they are getting better against all the other users. We are beyond R&D and into commercialisation.
The same device in the car can be used to pay for insurance parking tolls and that's how we turn the car into the next payment device.
