I don't know about regulations, but you are right about the blue light. Most white LEDs have low CRI, and that's why things look weird with them.
The reason they use low CRI LEDs is probably because they are cheaper and produce more lumens per watt.
Blue light does not damage things just because it's "adjacent to UV". And low cri is good enough for driving, you need to see whether there's a pedestrian on the side of the road, not to create a nice photographic composition.
I meant they were right about being too blue. I don't think that it damages the eyes because it's blue, but I'm pretty sure a really bright light can damage your eyes.
