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.
It could be as simple as your eyes were much better back then.
I remember driving with sealed beams too.
