There have been plenty of flame-filled discussions about the merits of DRLs. Just do a quick search and you'll find a few. In the end, I look at it like I look at many things: Car manufacturers should give you a way of turning off optional (eg non-mandated) features in your car. Good manufacturers realize that in certain conditions any safety feature can change from helping to being a hindrance, and allow for each system to be disabled independently by the user. Smart got this one right... They turn it on by default (normally) when it's available and give you a way to turn it on an off on your own. (Same as the auto-locking doors.)
Now if they had only done it with the auto AC enable when the vents are set at front windshield flow only...
