How are they in snow?
The problem with HIDs is that they need a carefully set up projector housing designed specifically for the lighting arc unique to HID bulbs. While this does help to control the extra intensity, all bets are off on wet roads where you can no longer control the scatter and reflections off the wet surface. This makes it more uncomfortable and even harder for oncoming drivers to see at night.
Then you have the colour shifting from white to blue to yellow and back again as the car follows undulations in the road's surface.
In much of the developed world HID systems are required to have levelling systems to compensate for extra weight in the back of the car, such as passengers, luggage, etc..
If the lights are so bright that they require levelling when you have people in the back seat, then perhaps they're not fit for the general public to use.
We're talking people who forget to turn their lights on/can't be bothered to signal here... you really trust them to eveluate the need for levelling based on how fat their passengers are, then apply said compensatory adjustments to their headlamps?
