Just a crazy ass idea? Replacing infotainment system

[Drivemode]

Hey guys,

Basically, the idea is infotainment systems are usually pretty bad and GPS units are old, so why not convert your phone to having a much safer, simpler interface?

You can do things like control your music just by swiping your finger or answer calls without blocking your navigation view.

I built a basic version of this for Android at http://cf.drivemode.com (has a video that shows the idea)

What do you think? Too crazy? Better than GPS systems?
