You can already get certain kinds of data from your dashboard and in-car infotainment systems designed for the driver to use. We presumably have laws that specify what's legit (speed, radio, etc.,) and what's not (watching tv shows). Can't we agree that if a HUD limits itself it what's already available, and is less distracting than the already approved alternative, then it's a win? If it tries to do things that are illegal, then it's bad? That assumes that the existing laws already do a reasonable job of win vs bad, but if they don't - fix the existing law - but a device like this seems no worse, if the gestures aren't more distracting than reaching for knobs/buttons. If this device wants to do more than is legal in existing head units / dials / knobs then we have a legislative process to address that. I had a rental with a HUD, and it seemed to me (FWIW) that it was less distracting to use that to see speed / nav directions on that then to take my eyes further from the road to look down at the speedo or center console video screen. YMMV.

All the posts about ambient light in front projectors are, of course, true. But that has a silver lining for my family. It discourages daytime TV watching :) In addition, on my 96" screen, regualar SD, with less than DVD quality, looks AWFUL, hence one more reason to limit viewing. Of course, we've compromised this "advantage" with a 32" CRT in the family room, and more recently blackout shades in the living room :( Despite these latests of example of my lack of discipline, we're holding true to the original notion to a limited extent - we only have about 300 hours of bulb use in the 2+ years we've had it ( 3 hours / week ) I'm not trying to say "feature" is a net positive for consumers at large. I'd also add (sorry if someone else said this and I missed it) that viewing something on a screen That Big sets an immersion bit that you don't get on smaller screens. Theoretically, I understand that viewing FOV (distance / screen size) allows for this with a smaller screen, but that has not been my (albeit limited) experience.
