I don’t see why this is downvoted — when self driving cars are a reality the car windshield hud will become one of the highest value “displays” around. The computing infrastructure to support this display will also be highly controlled compared to previous generation consumer computing hardware — I think the only model for computing on this surface will be “walled garden”s — if Apple doesn’t want to be locked out of this interface they’ll have to build their own platform for it.
