The problem with e-tolls, besides putting toll collectors out of work, is that it is an invasion of privacy. It allows government to track your movements by knowing what day and time you went through a toll booth and in what direction. We don't need more Big Brother as with the NSA .
It appears that the billing and collections are most costly and less effective than keeping the toll keeper.
More timely bills would help! You send over a month later if at all then rack on late charges and THAT is why some people aren't paying!
