Electricity left "in the tank" gauge.

[JoulesThief]

Has anyone ever confirmed with pictures of the electric "fuel" gauge, what 80% charged, and 90% charged looks like on the dashboard? Kind of curious as to how the charge rate slows down considerably when you get close to full charge.

The gauge faithfully reports the usable SOC (State of Charge). How this relates to the absolute nominal capacity of the battery is unknown and doesn't really matter. Someone with a home energy monitoring system or a data logging EVSE could document the charge taper with AC charging. I don't have equipment to do it, or I would have done it already.
