I have and I will stand by it till the day I die. I will have HUD on all my future cars (if available, and i believe other car makers will also offer them).

All are adjustable. No compass or rpm though.

Bright daylight is not a problem. It should never be a distraction because one should ALWAYS watch the speed while driving anyway. It is not IN YOUR FACE but it is much closer than the dash speedometer.

p.s. It is a proven technology used by the BMW Formula 1 team.
