The DeLorean was famous exactly because it wasn't 80's aesthetics; it STILL looks like the car of the future. But the instrument cluster? it's made of cheesy analog gauges that bounce with the fluctuations of the system voltage. It desperately needed an upgrade. (but I have all the original pieces and no parts were cut in the process of the mod ;-)
But that's part of the experience, is it not? Analogue gauges!
Also, assuming you're the one that did this modification; How long does it take for your instrument panel to boot? Fast enough to see the tach needle (or replacement thereof) jump up as the engine starts and then bounce back down to normal? Being in a car where I wouldn't be able to see that happen would be… surreal.
My kernel takes 2 seconds, and the userspace takes about 4, mostly waiting for Xorg to initialize the display (which I could probably improve using a hardcoded xorg config, rather than autodetect). The real killer is BIOS though- my FitPC 3 takes about 7 seconds to POST. However, I power it on when the door opens, rather than when the key turns, and one of these days I'll get it connected to my remote unlock button. The microcontroller is always on and consumes almost no power. I would buy a new PC if I knew for sure that the post time was less, but nobody ever advertises that statistic, and anything based on BIOS/UEFI tends to be abysmally slow.
Meanwhile the display rendering should be within ~50ms of the measurements from the microcontroller, so the tach and other measurements feel really "tight". (the tach is that curved column of horizontal bars on the left)
You ruined it!
