Rather than the GOM's psychoanalysis, would rather have a simple meter showing how much actual charge is in the batteries.

The problem is, especially among new EV drivers, they want to know how far they can drive. Not how much charge is in the battery. Yes, with experience the driver would benefit more by knowing the state of charge, and not some arbitrary distance that may or may not be accurate for the upcoming drive. The car can't know that your previous drive was flat terrain and moderate speeds, while your upcoming trip is on the freeway and will be crossing a mountain pass (or two). But the GOM at least gives the less experienced some idea about how far they can drive. With the Bolt displaying a min and max value, that helps the driver at least consider what the upcoming trip might actually need for range.

Is it possible like on the Mach-E to reset driver habits to none?

You can reset your most recent driving record (distance and time traveled, average speed, miles/kWh), but I doubt the GOM calculator is wiped by this. I reset my data every time I fully charge, and the GOM doesn't change when I do it. It's still basing the estimated range on the most recent driving data.

I know where the GOM is on my 2019 Bolt EV; but where is this "DIC" (whatever that means) efficiency average that disagrees? Thank you.

Driver's information center. The display directly in front of the driver. The GOM is in the DIC. This is separate from the infotainment system display that is centered in the dash. Both displays show your efficiency average, and they often disagree until the car's been driven 15 miles or so. After that they are usually within a tenth of a kWh per mile. At least the displays in my car do.
