The car tracks energy used and distance driven. Pretty easy calculation for the car to handle. I don’t think they’re doing anything stupid to mislead you. Mitsubishi had that problem, led to lawsuits that were ultimately successful for vehicle owners.

I’m recording about 17.2kW/100km right now, which translates perfectly to the observed battery consumption I’m seeing

We don't know exactly how it was programmed, but you can very easily reverse engineer it with paper and pencil and compare. If you have CarScanner like tons of us do, record the energy available at the start and end of your session, same with your odometer. You can now calculate energy consumed and distance driven. I hope I don't have to explain to anybody how to use those values to calculate and compare against the car's reading.

I did this with my RAV4 a few years ago to check it's L/100km calculation using the amount of gas required to fill the tank. You know, since I'm a nerd lol It was 100% accurate.
