I'm pretty glad that didn't make it to production. As a JDM owner, I would have to learn to speak Japanese just to operate the radio and aircon.
In the photo, it looks like the screen is a cathode ray tube. I don't think colour tft panels (ie. laptop screens) had even been invented at that time. If they did exist they would have been very expensive.
The design on the user interface looks like it may have had touch-screen as well as voice.
