We don't have DRL because it has been studied and shown not to not make a difference. Other countries should catch up to us in not requiring things that don't do anything useful. (depending on the time of day, sometimes DRL helps, but sometimes it makes things worse - overall the difference works out to not significant)

OP is talking about cars at night without any lights on. DRLs would definitely make cars at night safer than car without any lights at all.

Not to mention, I said "at least" DRLs because DRLs are a watered down version of what the European studies show as safer, which is headlights on all the time. In the US, the brightness of DRLs is limited, so the studies are shit to begin with because they're not even using the right variables to find the safest solution.

And most new cars have an auto setting for headlights (and have for a while) that most people just leave on auto. (At least for their own cars. I never totally trust what's going on with a rental although I assume it's pretty standardized at this point.)

I'd like to see those studies because both as a driver and on bike DRL makes a huge difference. Maybe less so with stroads and massive parking lots where you don't have a lot of curb-side parking and visibility is generally good.

https://en.m.wikipedia.org/wiki/Daytime_running_lamp says the study was in 2008. I can't find the study itself, but you might have better luck.
