Do you wear hi-viz or reflective clothing while riding on a fairly regular basis?
If so, what items do you use when? Some bicyclists like to wear clothing like screaming yellow jackets on long rides so that they can be seen from afar. Other cyclists wear various reflective items such as vests during shorter rides (such as commutes) so that the uncaring motorist's excuse of "I didn't see him/her" wouldn't hold water while being questioned by police or in court.

If you don't wear hi-viz clothing or choose not to, that's fine with me. I didn't begin this thread to start an argument.
