My wife's Acura TL has HID headlights.  The HID light pattern is
closer to e-code than old DOT and they are insanely bright.   When
cresting a hill or incorrectly aimed HID headlights will blind
oncoming traffic, but otherwise the beam cutoff is below the oncoming
driver's eyes.  The one side of HID that is not often not talked about
is they put so much light so close to the car that your eyes adjust to
the bright light and will not see much beyond the low beams.  This,
and the color of light actually hurts night time depth perception.
HID is a case of too much of a good thing being.. just too much, like
LED retina-burner strobing brake lights and turn signals.
