There are definitely different standards.
http://en.wikipedia.org/wiki/Standard_illuminantThe eye white balances pretty easily. If the majority of the headlights are 4300K, then anything above that will look blue. But if all majority of the headlights were 6500K, then the few 4300K bulbs would look orange, and the former would appear white.
All the lights in my apartment are 5900K CFLs with a CRI of at least 94, everything looks nice and white when I'm inside. But when I'm outside at night, under sodium vapor street lights my apartment looks like it has blue bulbs.
