Always amusing to read American opposition to common sense that the rest of the civilized world has implemented many years ago. Like the metric system and daytime running lights...
But inevitably the US will one day have both. And with respect to DRL, one can only hope that TAIL-LIGHTS <on> will be a part of it! In visibility limited daytime divided highway driving, it is at least as important to be able to see the tail-lights of the vehicle in front of you as it is to see the headlights of the vehicle behind you.
