LEV,ULEV, SULEV, PZEV

The automotive industry is under pressure from the federal government to further and further reduce emissions.
That's a good thing.
The automotive industry is constantly revising it's engines and creating new technology to achieve the goals set for them by the government.
Great.
So they have these various designations...
low emissions vehicle....LEV
ultra low emissions vehicle....ULEV(see where this is headed?)
super low emissions vehicle...SULEV
and now we have the latest technology...
Oh, I have to say, "super low" kind of annoyed me, but I'll let that slide....
Partial Zero Emissions Vehicle...PZEV
Partial Zero?
what the fuck is a partial zero?
zero is an absolute. either you emit zero emissions, or you emit, oh I don't know....some quantifiable fucking number of emissions!

I would have rather they called it Super Uber Duper Ultra Low Emissions Vehicle.
SUDULEV
It would sound like a Russian chess champion or something...

I have now adopted this as a numerical value in my daily life.
"Dude, you have a partial zero chance of that woman going out with you "
