my crazy idea for "windows for cars"

What if windows for cars, Microsoft's hypothetical answer to carplay was open.

Here's my idea of what it would be like:

-runs 3 Operating systems: windows RT, android fork, and a hypervisor to combine them.

-it have a metro interface. android would be forked and in the backend with the hypervisor working the "fuse" between windows and forked android. the front end would be all metro.

-it runs android to avoid being a solution for just windows phones. It would be fully compatible with android users to introduce them to metro and get them addicted. If not, they can still use MS services from the Windows for cars.

The main thing though is that windows for cars can be an appealing option to anyone that doesn't use iPhones.. -since android phones use micro USB, it wouldn't be a problem.
