I almost always use my CHL instead of drivers license when asked for ID. I rarely carry my wallet and drivers license which I tend to leave in the vehicle. I generally carry the CHL in case I enter a "public building" or other area requiring the CHL (not that Oregon law requires it to be in your possession but I'd rather not be charged and then produce it). Other times I use it because I simply want to say "yeah I might be packing" (think at my college, etc. where they would expel me if I open carried but they can't search me to determine if I'm concealed).
RARELY do I present my drivers license as ID.
