Why are HUDs not used more in cars? [closed]
In military and civil aviation, I’ve been told, head-up displays (HUD) are rather common nowadays. The technology is not that expensive anymore. Is there a user experience reason for HUDs not being widely deployed in consumer automobiles (and motorbike helmets)?
Without trying too hard, I can think of a number of probably useful features that go beyond moving information (like current speed) from the dashboard to the windscreen, most of which have been showcased already:
- Highlight pedestrians, animals and other obstacles, especially when it’s dark outside.
- Show navigation hints.
- Virtually remove the hood when parking.
