HIDs don't need to blind anyone, and shouldn't.
For sure the area that lights up is no bigger than the halogen coil - it just gives off more light. As no lamp mounting is exactly identical, the bundle may be slightly misaligned.
It is every drivers responsibility to make sure that their lights are aligned correctly.
I hope anyone on this site who considers HIDs is wise enough to do so.
My Honda garage aligned my aftermarket HIDded lights for free, even though I did not buy the HIDs from them, nor the car... Maybe I'm just too good looking?
The Insight has projector lenses as standard. A RPITA with the halogen candlelights, as they give so little stray light that anyone not facing the light bundle hardly sees the car at all. The HIDs have cured that somewhat.
