If I were to wager a non-crazy, Occam's Razor-compatible bet, I'd say the author had a bad day, saw one too many digs at the quality of their decade-long work, got pissy, and decided to call it quits. I love popcorn-munching news as much as anyone, but this probably isn't it.

"BMW says its laser system is 1000 times brighter than LED headlights but uses half the power." Yeah, that's bull, unless they're using some very creative definition of "brighter". LED headlights put out about as much light as do standard halogen incandescents, about 1000-1500 lumens per fixture. A million lumens? You'd be hard pressed to tell that apart from the sun. Also theoretically impossible, as LEDs are already at 10-25% maximum luminous efficacy.

Decent LEDs are, currently, about 6x less efficacious than the theoretical maximum of any light emitter, as measured by the human eye. Incandescents are much poorer performers, of course.

Well, I'm glad that you, specifically, have never had that issue. Might you have noticed the large number of complaints registered in the years since HID lights became common?

Legroom? I also value the lack of cavity searches.
