Strange, all this features with the Android Auto I can already do with my Moto X. Ok, is not displayed in the car's big display ( but I don't have one! ), but I can do almost everything without using my hands.
MOTOACTV is also a precursor to this wearable watches, pretty much capable at least the notifications. Nonetheless, this was more sports oriented.
Voice actions and Motorola Connect are the best parts about the Moto X, in my opinion. Like you, I don't have a fancy dash display yet either, but the experience with the Moto X makes me long for the day when one could take over UI / input control automatically without even taking the phone out of my pocket or handling it at all. I will go in for an upgrade in auto at that point!
I didn't see Moto X listed as an initially supported device for the forthcoming Chromecast "screen mirroring" feature either- although maybe I missed it. Hopefully it comes soon. I use the Chromecast constantly and would be all over this.
I had such high hopes for a Google-owned Motorola too.
