I know this will never happen in Texas but California is considering a bill called the California Clean Car Discount Act that will impose charges and grant rebates based on a car's carbon dioxide emisions. "One-time registration fees of up to $2,500 would be levied on new gas guzzlers, such as Hummers, Dodge Vipers and Chevy Tahoes. Some cleaner sport utility vehicles, pickups and minivans would be exempt from any charge, while the Toyota Prius, Honda Civic, Nissan Sentra and other fuel-efficient cars would get hefty rebates."
Similiar laws have been enacted in Canada, Finland and France.
Maybe a tax like this would discourage these idiots from buying these stupid gas guzzling polluters. If not, I'll be happy to take my rebate check.
