thanks, I suspected about the Linux kernel (that's what makes sense for completely new hardware devices any way) and if it's well done it can be as good as Android (just for a while:), but they sure will lack the weight Google can give, as well as a giant ecosystem of developers. I think there is no way any single car company can make a new platform evolve as fast as Android is heading to now. For instance, any car could have a Nexus 7 in the dash without the need for higher price of the car (R&D as well as custom hardware), and expensive car systems will get obsolete faster then standard and successful devices.. I think car companies should agree on a docking system for tablets as soon as possible for out own benefit.
Anyway they should be benefiting already with Android's popularity because they are using nVidia Tegra CPU on Linux kernel, the same combination as most Android tablets, and nVidia have been paying attention and updating Linux drivers mainly for this reason ;)
