Yes I know that.
The point was this, in the previous gen, you could place the lights on manually- however when you turned off the car, the lights would turn off automatically after 15-30 seconds, or depending what you set it for.
When you started back up, lights were on, and you essentially could have your headlights on all the time as you drove.
Sometimes, you want your headlights on regardless of lighting conditions. You want that visibility. And if you turned off the car, you didnt have to worry about a dead battery or alarm going off.
Now in this generation, it seems that you can turn your headlights on manually- but the car (for all its advanced electronics) doesnt seem to know how to turn off the headlights after 15 seconds.
Rather it would prefer to warn you with an alarm.
In other words, someone decided to change the function to have the cars alarm chime in when you left lights on, to get you back there to turn them off, rather than code the electronics to turn off the lights and not bother warning you with the alarm.
Seems like some engineer was too smart for himself or was not accustomed to driving a lower to the ground car which would have given that engineer the perspective that sometimes you want headlights on in the daytime for safety visibility concerns.
