No, it's because on anything but billiard table smooth motorway HID's have shut a sharp beam cutoff that they fry your retina's. Have a car behind you with HID's (I'm talking Audi's, BMW's and Merc's so factory fit stuff...) and when the cars follow the undulations in the road it looks like they're flashing you.
HID's, great for seeing the person who is just about to crash into you because he's blind because of your HID's.
Not if they're correctly setup factory fit.
