This doesn't apply to current headlight technology, but I think when driving around urban and inner city, I think manufacturers should add a low power headlight mode, which under powers and dims the headlight. Less light on the car means you'll use the street lights to guide your driving. And when you get on the highway at night, you turn it back on to full power.
This is exactly what they have now, and is one of the specific things I'm arguing against. The appropriate time for DRLs is in the daytime; running them at night can be dangerous to others with no apparent benefit for the driver. A "lose-lose", if you will, and even somewhat counterproductive to the very reason why DRLs are meant to be implemented.
The default is that you are easily able to misuse the system accidentally if you don't go out of your way to educate yourself on what it is and how it should work. Instead, I believe the default should be idiot-proof, and if an owner wants to misuse the system, they should need to be an idiot with intent.
Somewhat off-topic, the lights on the dash aren't always super intuitive. You'd only know the high beam icon if your dash included the corresponding lowbeam icon. One funny one I've heard is the "butt on a piano" icon. aka the low tire pressure indicator.
