Correct me if I'm wrong, but wasn't it already illegal to steal gas?
If people are still doing it, does anyone actually believe that passing another law against it will make them stop?
Do you think that anybody desperate enough to steal a tankful of gasoline will be deterred by this threat? I think that this will just result in more unlicensed drivers on our roads. The kind of criminal who drives off without paying for their gas will also continue to drive after losing their license.
The only thing this law (and others like it) accomplishes is an erosion of law enforcement's already questionable credibility.
Maybe we should pass a law against that.
