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:

        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.
