So, for a good long while now, most cars and trucks have come with an auto setting for lights, yet I constantly still hear about people who left their lights on or see vehicles on the street in the dark who don't have their lights on. Are people ignorant, stupid, or is it something else? Is there some magic benefit to not using the auto setting? I had my 2004 Pontiac Grand Prix for 15 years and never once took the lights off auto. I've had my new Mazda for a few months now and have also had it set to auto the whole time. Never had any issues and am happy to have one less thing to worry about. Just has me scratching my head...
