Given the number of drivers I see using high beams continuously I think that's the way they've "solved" their lighting issues. Once the plastic headlight lenses turn yellow and cloudy I guess that's a cheaper and easier fix for them than restoration or replacement. If it impairs others around them who cares? Many of them are too busy constricting their pupils with bright phone screens to even notice.
It was pretty cool when DOT restrictions on composite headlights finally relaxed. Now, I'm wishing we were back to a very limited set of sealed beam options. It's really utter chaos and anarchy out there where lighting is concerned. So, I don't waste my energy trying to talk people out of LED and HID conversions. They're going to do it, anyway.
