It would be great if there was an option to input a reduction in expected range when towing. Many ev models now can tow, but range is half-ish.
when you add a car to your profile, you can add profiles to that car, that have independent configurations. You can then for example add a configuration with a trailer, that has a higher ref consumption. If you use live data and select the right profile before driving, that will also store the related consumption for that configuration automatically.
