My understanding is that in official terms, this idea has been a non-starter, and I am personally against it because it removes the burden from gas guzzlers via the fuel tax. In other words, cheaper fuel for all, spreading the tax burden out onto those who choose to drive more efficient vehicles.

Basically they are just trying to change the color of the lipstick on the pig and charge the owners of more efficient vehicles disproportionately more for the damage that the larger vehicles do to the road. In a nutshell, it's crap.
