I forgot which marketing name it was, but one of Honda 1-motor systems that used the motor in clutch pack had a major design oversight that it can't handle a traffic jam in an incline, which happens in (of all places)Japan; the HV battery runs out and the car needs to be towed and/or driven at higher speed to both cool down and fill back up. Generator plus traction 2-motor systems feel stupid but it's necessary to cover those situations.
