Which administration? It's a global industry. California cares a lot about air pollution. Has to because otherwise the Los Angeles basin becomes uninhabitable. Most European and many other countries care about mileage[1] and enforce it via stiff fuel taxes. Lot of developing countries have very bad problems with smog. Most would leaders with the exception of the particularly stupid sort you find in the US are getting spooked about global warming. Probably auto exec's themselves are getting spooked.
