Far from all. It is not a requirement. GM was among the worst on putting DRLs on lots of their cars.
And to comment on the list from that site that qam1 posted, there are three Audis in our fleet, two ‘99s and an ‘07, and none of them have DRLs. If Audi did it, it was for a very short time and not in all models. I’m pretty familiar with their cars. Hmmmm, just thinking about it, they do have those stupid LED front running lights that outline the headlights on a couple newer models (A5/S5, maybe the A4/S4). They’re more of a style thing, and I personally don’t like them a bit. That may be what they’re talking about. But they are a lot less light than a low beam DRL like GM did / does so much of.
