And yet, in some US states, it is still currently illegal to have 'Day Beam' headlights or run your headlights during the day because of the slight extra load on your alternator, ....

Of course, in some parts of the world, it seldom gets dark enough during the day to need the use of headlights!

As I pointed out above, daytime headlights are legal everywhere in the US.
One reason to run them is to make your car more visible to others on the road.

Whether it's actually useful in full daylight (unless very cloudy) is questionable, but there are some countries where not only it is legal, it is mandatory.

But you know the car with the lights on is operating, whereas the one with lights off is dead in the water. Makes a difference if you're keeping track of potential hazards.
