High beams are not redundant, because they are aimed straight ahead. Low beams are aimed downward towards the pavement in front of you.
A few cars have started having high beam HID systems. However, I have a concern about these - don't they make it difficult to use high beams to "flash" someone to pull over (or for oncoming cars to lower their high-beam headlights)? I say this because HID typically require a few seconds to power up to full brightness.
