I don't know if you people up north know what kind of bright, sunny days we're talking about

At least twice a year (like today!) it is really bright here!

, but I think that DRLs become more dangerous in this bright sunlight.

I don't get it. I have never been blinded or distracted by DRLs or daytime headlights whether in gray Seattle or in Mexico at high noon. I *really* don't get it.

I suppose your answers will be opposite to this anyway.

Of course (doing the work of Beelzebub as always!!).

Our weekend provided part of the various DRL cases-in-point. Conditions ranged from really bright (Eastern) Washington sunshine to sudden charcoal-grey thunderstorm conditions (that created all the swell new water hazards). On fast transits on 2-lane highways, I was happy to see DRLs oncoming, whether in the shimmer of hot blacktop or the dull murk of thundercloud overcast. It is my opinion (backed up by nonexistant research!) that "lights-on-for-safety" / DRLs help to moderate FPB (Fatal Passing Behavior) -- make it clearer, *earlier* that you have oncoming so you can pause to reflect on rate-of-close issues...
