DRLs in cars use your low beam at 30hz instead of a 60hz current (so it is less bright than a proper low-beam – it also messes with aftermarket HID systems, much to my dismay).
Speaking as someone who lives in a country with manditory Daytime Running Lights, I assure you, I notice when someone has their highbeams on even on a sunny day.
Motorcycles in Canada run their stock low-beams anytime the bike is turned on (I thought this was standard south of the border as well, but don’t know for sure).
If you don’t think you are bothering other drivers riding with a high beam on, simply have a buddy sit on your bike, high beams on, and then sit in your car 50 feet away in the opposing lane. If you’re okay with that, go for it. It is all about the golden rule. Me, I notice it, I strongly dislike it, I won’t inflict it on others.
I’m curious if there is a report on this more recent than the Hurt report…
