Well, I live in serious critter country, Lake county is one of the primary hunting zones for California. And, knock on wood, I don't have problems seeing deer. Usually I spot them well before they try to cross in front of me. Maybe you just need to slow down, and not outdrive your eyes. When my vision is impaired, including by darkness, I slow down.
And there is no way I'll see a blue-white glint if I have a blue HUD sparkling on the screen.
The HUD doesn't dominate the windshield, you know. And it's not as bright as you seem to imagine.
