I will be nice but is it really such a big deal assuming she is not doing something stupid like using a cellphone while driving, her left hand should be right next to the headlight controls. Takes less then a second to turn them off.
I notice on all the family cars ( as I only owned jeeps ) that the ones with automatic headlights usually have the headlight controls out place. As example my brothers 2000 town car has the switch to the left of the instrament panel making anyone remove there hand a good foot away from the steering wheel to turn on the lights, solution give it auto headlights that turn on and off by them selves. Silimar to a Honda and a volvo that was own by other family members.
I do think my 99 Limited WJ had auto position on its switch but I think i ever really used it. as it too easy to turn the lights on an off.
