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.

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.

NASA's software teams are also remarkably small, and manage to produce code with one of the lowest defect rates of all time. (Space shuttle code had 0 defects in 500k SLOC!)

Just goes to show: quality over quantity!

Liftoff and re-entry are completely automated. The astronauts are passengers and don't interact with the craft during these maneuvers. This was the case even for Apollo.

The Crew Dragon seats also have physical arm-rest controls. Those arm-rest controls are what the astronauts use under acceleration, and IIRC they're primarily comms controls.

To be fair, I can't think of anything better than LabVIEW for rapid prototyping and development of complex sensor interfaces.

My car has a holographic HUD that displays on the windshield, and responds to hand and voice gestures. (The HUD is _awesome_, but the gesture recognition is hit or miss at present).

I agree with you that touchscreens in autos are garbage. However I don't agree that physical or haptic switches are the _only_ solution. I think touchscreens in autos were just a technical stepping stone towards something new, like this combo of holographic/gesture/voice control UI.

Basically all cars monitor battery voltage. Many models even have a dashboard gauge for it. But what is that information useful for, other than diagnostics? Why give it dashboard real estate? Besides, you can always pop open the hood and check the battery with a $12 multimeter.
