How about the rear fog lights on high buck European (most except VW, that I?ve noticed) cars sold in the US. These blindingly focused red lights are required in most other countries, but idiots with no common sense like to run them on clear nights in bumper to bumper traffic on well lit roads. I tend to lose my cool because the fricking dealer didn't tell them not to use them when there's no fog or even show them what that switch is for. And god forbid any of these fools would RTFM.

Bright blue fog lights and headlights (I?m talkin? about incandescent, not HID) are annoying to oncoming traffic, and as far can tell, since they filter out the yellow light (the more useful color, hence many fog lights are yellow), they?d be insufferably difficult to see with. They don?t look cool to me, they look stupid and dangerous.
