Ok, look. Will it make you happy if I rephrase the original question thus:
"Why do those people who put very bright lights in their cars ON PURPOSE do it?"
This eliminates all the people who have aiming problems and all the people who put in brighter lights than they intended to, leaving only the intentionals, which was the only group I was talking about in the first place. Sorry I didn't spell it out from the outset and avoid all this dissembling.
