Is the Drivelog Connect even necessary?

"Drivelog Connect allows your car to speak to you. Your car directly connects with your smartphone. All the information becomes available at your fingertips."

Many of the features the app offers could be made available in the car's console/monitor.

Like: - automotive diagnostics, display of real-time driving behavior(should you really be looking at your Smartphone while driving), Logbook for recording and storage routes...

I don't really see benefit of this app.
