My impression is that the folks supporting this (and other measures that make driving harder) are vocal but a minority, and the majority would be opposed except that it simply didn't take these issues into account while voting. (I know I didn't believe they'd actually manage to do this.) That's just based on talking to the people I know, not on any survey. I guess we'll see if actually having to pay the tolls pisses off enough people to change who gets elected next time...
