No, not at all. The HUD is positioned so that you're watching the near-field road ahead. The hologram is projected so that it appears maybe 30' ahead of you, on the road. The HUD also has minimal information. If nav is off the HUD shows you your current speed and the speed limit only. If nav is on, the HUD gives you a simple map display showing your next turn, and that only appears as you approach. It's a really excellent system. Not at all invasive or distracting, and MUCH better focus- and attention-wise when using navigation vs, say, staring at a smartphone or console display.

It is opposite. Don't need to focus off from front glass.

I'm talking about having to move the focus from the road to the windshield. That still takes time. If the HUD is "at infinity" then it's ok, but would you need special glasses to make that work?

I use the term "holographic" for a reason. The HUD appears to be projected at a distance of, say, 20-30', and is positioned low on the windshield so that it essentially overlays on the road. You do not need to refocus your eyes on the windshield. Focusing on the road also focuses on the HUD projection.
