With my ID.4 AWD, ABRP tends to underestimate range achieved by 10 to 15% which makes accurate planning impossible. An optional "training" setting allowing us to input actuals after a trip and have ABRP compare to its predictions and learn would be very useful in order to match ABRP's computing to the car's capabilities for those of us who think an OBD dongle is too risky.
