Can't they simply get units with a 2800K white point?

Because of your eye's sensitivity to different frequencies, the "warmer" colors require more energy for the same effective lighting. Hence, highway departments choose the "daylight" option to save energy.

All the studies I've found seem to say something along the lines of "blue light disturbs sleep", which seems like exactly the needed effect if you're driving at night.

Yeah, until you drive out of the highly lit area. Then your eyes will have to take some time to adjust to the low light.
