In addition to taxing the amount of actual gas used, I would like to see a tax applied to account
for the amount of pollution caused.  It could be assessed when the vehicle registration is due.

I envision it to be a function of actual mileage, EPA mileage estimate, and actual readings from 
the smog test.  Cars would have to get smog test every year, they would have to pass, period.  The
first year the mileage would be  calculated ( miles / age of car ), after that it would be the 
difference between the odometer and what is on the DMV registration form.  The calculation could be
simply done with a reprogramming of the smog computer.  The smog certificate would have the assessment
on it and a machine readable copy of the data ( OCR, bar code, etc).  Their would have to be heavy
fines / imprisonment for failure to comply, fraud by the consumer or tester, etc.

This has the advantage of levying the heaviest fine on the heaviest polluters.  To help relieve any
burden on the poorer segment of the population (since they tend to own the older, dirtier cars) a
variation of Bush's EPA pollution swap could be used, where industry buys the car for limited 
pollution credits, but the payment is  towards a newer cleaner car made available by the state.
