Same as the auto off high beam,don't think people appreciate being blinded,particularly trucks,as you come over a hill,(the truck driver)coming towards you is well and truly blinded by the time the D4 picks up the headlights,and switches to low beam.
I removed the fuse for the rain sensor which converts the sensitivity adjustment into variable delay for intermittant operation. I encounter more bugs than rain and didn't like the inconsistant auto operation anyway.
