I'm talking about those insanely bright blue/purplish headlights that blind other drivers over a mile away. It doesn't take too much sense to figure out that they are causing/going to cause accidents all over the place because of people having to look away from the road due to the eye pain/glare they cause IMHO. Yet they are gaining popularity again, and the new Mercedes even use them for the daytime running lights, which are even blinding when used full sunlight.
Edit: added a second poll which is basically the same question but divided by location, since from this article: http://www.usatoday.com/money/...s/2001-06-07-xenon.htm that RagingBitch posted, HIDs used in the U.S. are actually aimed differently than HIDs used in Europe due to government regulations in both locations because of the lack of uniform roadsign lighting here. (European HIDs are actually illegal in the U.S. and vice versa because U.S. headlights are actually required to have the cutoff above the vertical some and out to the sides more while European ones are prohibited from doing so.
