With emissions in China and India etc , its a bit like using a stirrup pump on the Titanic :rolleyes:

I agree completely.

Plus, what is the actual lifetime environmental cost of all this extra s*** they fit?

AFAIK, there is still no economic way to re-process the lithium out of the hybrids out there....
 
It is a urea based additive which burns in an after burner in the exhaust and cleans up the dirty particulates,

You could just pee in your tank then!
Friend of mine has Audi A6 with same system. He bought a container of urea and fill the reservoir himself rather than paying the dealer to do it.
