Ok, this one is a little more serious than my "Power off" question. Over the last 20 years, I've gotten into the strong habit of always turning my headlights on when driving -- any time during the day or night. It's an automatic habit to turn them on when starting my other cars, and turn them off when stopping. I've *never* liked the "Auto" setting on cars since they first appeared, so I never use "Auto" headlights. For instance, when it's raining or snowing out during the day, or the wipers are on, the headlights don't always turn on (depending on car make model and year). I just like having my headlights on all the time for safety so people can see my car. It was doubly important when I had a Delorean, since it was so low to the ground, TWICE, I almost got run over by a huge SUV changing lanes because the driving just could not see my car out their rear view mirrors. Anyway, with the Model S, there is the "Auto" setting, which I still hate. The "On" setting works fine, but like my other cars, I have to turn them on and off manually each time I drive (The MS doesn't remember the "On" setting). If I leave the headlights in the "On" position and park and get out, I get a nag screen/error message that I've left the headlights on (and here is one good reason to use "Power off" which would also shut off the headlights). What I'd like to see in the MS interface is a headlight setting that's "On when driving" so the lights turn on whenever the car is not in Parkl.. And they automatically shut off when leaving the car WITHOUT the nag screen/error message. And if I need the headlights on when not driving, then I can still turn them on/off manually. So to do what I want, it's either ignore the nag screen every time and the car will shut them off itself, or use the "Power off" button, which you've all convinced me that I don't need to do. And it both cases, I still have to manually turn them on when I return to the car, as the MS reverts back to "Auto" mode.
