Given how much GM is pushing Siri Eyes Free Integration, I would imagine it would not be profitable to buy Tesla. Probably, as you said, iOS in vehicle or iOS integration.

Which is to say not very much? I was aware it was on the horizon through promotion by Apple, but I only accidentally discovered support in my new GM vehicle. Its usage is non-obvious and there was nothing I came across in the promotional materials or indication through the dealer suggesting that it was available.
GM has had comparable stuff in their Buick line (very popular in China), Ford just advertises on more tech sites because of Microsoft. Siri hands free is also in the some Honda models.
Its the one with the "dude" who is listening to his messages while his wife is in the passenger seat. The last message is about a tattoo. Its another "stupid husband" commercial.
