All I can say is I drove plenty fast at night when all cars had sealed beams. Then halogens came out and they were like - balls. My acura has xenon lighting and i do love them.I just think people make too big a deal re the hid's. Amazing I didn't die driving all those years at night with sealed beams.
I think a person's view of the stock headlights depends on what they were driving previously. If they were driving an older Mustang, they probably feel these newer cars are as good or better than the older models. If they were driving something with HIDs, or better Halogens, they probably think the stock headlights are/were atrocious.
