why? I am seeing other manufacturers blindly copying them too :-( Of course you know what I am talking about if you have been just mildly observant on the road. Audi turns off the DRL on that side when the turn signal is activated. They believe with DRL on, you will not be able to see the turn signals! I recall seeing a Chrysler vehicle recently which had implemented the same behavior. There can't be a technical reason for it, correct??
