Right when weighting the benefits the big one is the fact most people use GPS navigation, having it via HUD is a significant safety boost. I'd say the same for speedometers.
Other situations are still not super useful and probably won't get used. Can you meaningful respond to text messages with voice? Not quite, yet at least. Can you skim read them? Yes. That is not super distracting but still enough of a distraction in some cases. But I can't think of many use-cases that are any worse than a bluetooth headset voice conversation.
