TLS,
Another view to consider...
I think of myself as pretty safety conscious, I generally drive with my lights on all the time and I religiously wear my seatbelt. But, I have both disconnected the DRLs and disabled the seatbelt chime. For me it's about being able to control what the car does - not having it assume things on my behalf.
I like to be able to sit in the car while waiting for someone without the stupid seatbelt chime constantly nagging me. I like to be able to start my car at my friends' house without my lights shining in the windows of their house.
So, if they gave me a switch to disable the DRLs when I wanted to - I would have left them connected.
Power to the people.
