I’d say that’s an interesting question to investigate further. The primary example given in that story is the radar equipped speed limit sign. It doesn’t tell you the posted speed. It merely tells you how fast you are going and that by itself apart from ticketing and making the speed limit signs more noticeable did more to effect a change in behavior than any other option. So maybe a goal oriented visualization could also benefit from some techniques like feedback loops?

Some of the fine fleur of information visualisation in Europe gathered in Brussels today at the Visualizing Europe meeting. Definitely worth to follow the links of the speakers on the program! Twitter has a good trace of what was discussed. Revisit offers a rather different view on that discussion than your typical twitter timeline.
