Long time readers of this blog will note that the topic of a congestion tax has come up numerous times, including the suspicion that the addition of radio frequency identification tags set the stage for it. Hopefully our government will take a page from the principles of open democracy and announce that they're going to trial a congestion tax for 6 months (aka The Stockholm Trial), produce a report and then put the ultimate decision to the people by way of a plebicite (aka a public vote similar to a referendum). By doing so, they can save face by not being blamed for introducing something that turns out to be hated but can also gain the credit if it turns out well. Ie, let the people decide.
For those interested, I've rambled on about congestion in the past so no need to be a bore. Here are a few links
