I'm with greg on this one. Digital gauges look way out of place on a classic truck like ours.
Another thing that doesn't make sense to me about a digital dash is that you can't easily understand the status of the motor.
With normal gauges, even a quick glance tells you that the needles are in the middle of the range..... No issues to worry about. With a digital gauge, you have to literally read each number, then consider what that number means in the context of the gauge. Oil temps could be 168, 171, 176, 181... Could be bouncing around between those values as you drive leaving you to consider if each of those values makes sense as you read them.
Tachometer would be even more distracting.... Constantly sweeping up and down by maybe 50RPM the entire time, rendering it basically useless. You'd spend WAY too much time looking at it to figure out what the heck number of RPMs the engine was actually turning.
Seeing an analog needle superimposed on a field of numbers in the background, with a "redline" area to warn of trouble is the way to go.
Digital stuff like that looks like it belongs in an 80s car like "Night Rider"....
Someday when OLEDs are cheap enough they will be a fun way to create a digital version of an analog gauge.
