The Democrats in California are EXTREMELY vulnerable on this issue. The legislation that they are trying to pass will ration or ban many cars and/or much driving in California.
I agree that roads, transportation, etc can be a major issue and I hope that Davis signs that evil bill AB1058 so that people will yell and scream, ENOUGH IS ENOUGH!!!!
However, I think he'll veto is because car dealers have more money than enviro-wackos.
