When the line is unexpected
A typically commuter is that driver who opens his application at the beginning of the journey to listen to his favorite music, or who turns on the car radio to his favorite channel.
He does not need a navigator, he is well aware of the roads to his destination and expects to find the traffic at the usual locations. During the journey, what most disturbs our commuter is to have to face with an unexpected queue due to unforeseen events.
The best solution for such a driver is to receive in good time from an application or car radio the information needed to beat the traffic. A perfect information would be a personalized voice message based on his location and destination.
