I kind of agree with you on the light switch. I think automatic headlights are fine for about 90% of the public, and especially nice for those folks who somehow forget to turn their lights on at nightfall. But I don't really need that kind of nanny-care.
That being said, I do like the fact that the auto headlights on my G8 come on and go off much faster than my 2002 Chevy S-10. If I drive under a bridge in the S-10 and the lights come on, it takes about a minute or longer after getting back in the sunlight before the lights go back off.
