This might not be unique to presidential speeches, but it’s where I’ve seen these things.

          Exactly.

          This is tech from the 50s (and you can find concept pics of it used in cars), it’s simple, cheap, and improves road safety a lot. I struggle when I have to drive a car without hud (I’ve first seen it irl around I guess 2005, yet not much changed till today, you still either have to pay extra or buy one of the top specs). Govs should just mandate it as a standard.

          Even weirder, when talking to ppl irl they mostly just say “oh that’s stupid” or “I don’t need that” (my father used to be one of those ppl too, and when he recently took his car to the shop & they gave him a temporary car without hud he bitched about it all the time how he doesn’t know how fast he is going (without looking away from the street)).

          (There is loads of such tech that work as good as 20 or 30 years ago, are generally cheap in terms of production costs, yet they remain a rarity - adaptive/radar cruise control, adaptive high mean beams, self-levelling low beams, cornering lights, IR cameras spotting & beaming nearby pedestrians and animals, etc. At least EU mandated assisted emergency braking so that the crashes occur at lower speeds or not at all. Megacorps just have to much influence/power/profits.)

          Nissan Silvia & 240 used this basic hud in 1988:

          Oldsmobile, also 1988:

            My father had a car with that when I was a kid and I still remember how much he loved it.

            As someone who’s never had it it’s always seemed like a nice to have and like it’s silly it’s not standard. Though it does look like you can get aftermarket ones at a reasonable price and that is tempting

              On my first car I used my phone for that (some Symbian Nokia maybe?), but only a few times.

              It didn’t have the battery for it really, and a bit of lag on them old GPS dedicated chips (it fit the dashboard nicely tho), but it proved the concept beautifully.

      Yes. They project the text from an angle so it reflects towards the speaker. Just like windows are transparent but can still reflect images in the right lighting.

      Yeah, they’re still reflective enough to mirror the text when viewed from the right angle.

      Here’s an example from YouTube so you can see what it looks like from the perspective of the one speaking:
