Partial Zero Emission Vehicle? [Spotted on a Toyota Camry]

PARTIAL Zero Emission Vehicle? PARTIAL?
Last time I checked, “zero” was a unique number. Unmodifiable.


This vehicle category was created as part of a bargain with the California Air Resources Board (CARB), so that the automobile manufacturers could postpone producing mandated zero emission vehicles (ZEVs), which will require the production of electric vehicles or hydrogen fuel cell vehicles.

I might have guessed it was California where words cost more and mean less than you think they do.
