More distractions for drivers
While I love the idea of having a modern platform in cars (I am still running a modded Windows CE dash system), I wonder if this is going to lead to lots of distracted drivers. Theoretically consumers will want access to the Google Play store for apps, but then do we really want kids playing angry birds on the car dash? This means it will really come down to the interface itself and which apps are contained in the specific stores run by the automakers.
Another question is about how these will connect to the internet. If you tether with your smartphone, you are looking at additional data plan and battery usage. If you connect it directly via SIM, then you are looking at a monthly service fee. In a way it reminds me of a fancy internet radio.
