Still not convinced.. 
The argument that something can be seen even from outer space if it has enough lights on is rather vacuous (see what I did there?
).
I'm not interested in seeing a car from outer space... or 1000 miles or even 1000 meters away. In an urban environment, which is where the safety value of the DRLs is only really relevant, if I look up the road I can only see 100 meters most of the the time. Parked cars, bends, hills, trees, buildings all get in the way of seeing further than that.
Any driver should be able to see a car at 100 meters in daylight, whether it has lights on or even if it doesn't, no matter what colour it is.
Only army vehicles need lights but they're painted kind of camoflage colours, so that's for a reason...
