Yeah the auto headlights (ie, turning on when it's dark) is fine and I have that on all the time. Mildly annoying that they turn on when you clean the window, though.I use the auto headlights all the time - their timing seems to be perfect.
However, I've tried the auto high beams a few times, both in light city traffic and on the highway. Their performance seems almost random at times, so I don't use them any more.
