First there was cruise control, constant speed Then there was radar adaptive CC, constant speed except when car in front is slower What about some sort of constant power output cruise control, where on a flat stretch of road you set the speed, but if the road starts going uphill the car can slow down (to some preset minimum) in order to maintain the original power output? There's no need to have the motor and battery work harder to maintain 75mph going up a big hill since most drivers slow down anyways. Is this possible? Good idea? Maybe I should post this in the suggested features section.
