My HUD is doubly the suck. I switched it off as soon as I found out how.
I do not need to have my speed right in the center of my line of sight all the time (especially being displayed as a number – I much prefer a gauge). The HUD floats in the air, right on the trunk of the car in front of me. (I have even developed a serious dislike for the field graphics in TV sportsball.) It can be nice to know, but I do not need to know it constantly and am happier to know that it is about what it should be more or less.
The other sucky thing about it is the dash frame, which reflects in my windshield on bright days. Yeah, I am finicky: do not toss your papers on my dash, I hate seeing stuff reflected in the space where I need to see actual stuff.
HUD could be ok if it was not directly in my line of sight all the time, where I could glance over or up at it now and then. And it could be useful for important info that is there for a moment. The way mine is I hate it.
