Leaving lights on

yes..almost all cars have an "automatic" setting where you never have to turn lights on or off, they do it themselves. When it gets a little dark the headlamp sensors turn on the lights by themselves, and when you shut car off they have a little delay time to allow you to exit the car and see where you are going, then they turn off. Usually about 1 minute.

I like to shut mine off, it is not at all necessary, but that is what I do.
