I drive a fairly low slung car (dodge intrepid), and especially when luxury suvs come up from behind (cayenne, escalade, etc), or approach from the front, I always get blinded by their HIDs. This happens practically every time (I've been conscious to check and compare every HID equipped car I encounter), so I'm sure it isn't just an adjustment/dirt problem. Even properly adjusted HIDs are significantly more disturbing to me than someone driving with (halogen) high beams on. I've driven enough cars with HIDs installed to know what an improvement they are, and I want to give them the benefit of doubt, but given the number of people with sensitive eyes such as myself, they are a liability and a disservice to your fellow drivers. This is why I will avoid buying a car with HIDs as long as possible. I do think they will become standard eventually, and I'm not excited about that.
