Dedicated small wh/mi display?

[medphys3]

Does anyone know if there exists an aftermarket small/micro display/screen that can show a customizable wh/mi?

I've looked at all of the displays that are out there, but none of them seem to have the ability to show this. Ideally, I'd like to have a miniaturized Model S style efficiency graph, but even just having the same 5/15/30 mile wh/mi number that the car shows with the efficiency graph pulled up would be fine.

The J Wardell MicroDisplays look like they'd be perfect to show this, but they've been sold out forever and I'm not sure if they are configurable to show this.

Any ideas?

And, yes I know the car can display this with its efficiency graph tool, but I'd rather just have the single number up front and not have to use up the full display.

About as useful as a permanent MPG display on an ICE car.

My thoughts exactly.
Just enjoy the drive, man. Forget the MPG/WPM statistics. They are not going anywhere.

If you want to upgrade you information awareness, get a radar detector and install the display within line of sight!

And I guess to add some thing useful, my lifetime wh/mi of 275 hasn’t really changed from new till now at 37k miles.
