With OEM projector or OEM reflector there is almost no glare because all of the light is angled under the cut-off line. When you retrofit HID's in a halogen housing it produces a tremendous amount of glare (even more so in a halogen reflector housing) and it becomes a constant blindness to the driver ahead or for oncoming traffic. Yes the road lights up better, but what people don't realize is the amount of glare it produces and then becomes unsafe. Not unsafe for the driver, it's actually great because signs that never lit up before are nice and bright, but it does constantly blind oncoming traffic and cars ahead of you.
Yes the 3 has projectors, but projectors made for halogen lighting (unless you have a 3 that has OEM HIDs). It's not designed for HID bulbs due to the way light reflects and projects out, hence you get a few glare spots, but it's not horrible compared to putting them in a reflector housing.
