do you drive with your headlights on during the day?
Engine on, headlights on. I have had two occassions in which drivers started to pull out and then quickly braked with the nose of their car just short of the edge of the road. I have 14K miles on the car and so this doesn't happen that often but I have to assume that my HIDs prevented them from pulling out. 
On the issue of foiling laser with HIDs; Police commonly aim at the headlight reflectors if the front plate is missing. I would think that since laser and headlights are different frequencies headlights of any type wouldn't matter.

Car and Driver (I know, not everybody's fav mag around here right now...) did a test regarding this effect quite a while back. They tested different variables to see how each affected detection range. On a black car (can't remember what model), with no front plate, headlights on, and an extra row of driving lights installed, the laser gun wouldn't return a reading.
Also, I forgot who made it, but there used to be a device that was installed in a front license plate frame that would emit an opposing IR beam when it detected a lidar gun's signal, thereby making the car invisible to lidar. It was connected to a detector in the car to warn you to slow down, since the protection only lasted a few seconds, or else the IR transmitter would burn out.
