The road less travelled

Via this article on the traffic problem in Toronto, I really like the idea of getting rid of standard road taxes and parking fees and replacing them with a satellite system that monitors travel, parking, etc. for every individual vehicle and charges accordingly. The customization is great - It makes it super-easy to reduce pollution and congestion by pricing the grid strategically. Besides some privacy concerns and the inconvenient fact that any politician who introduced this would pretty much be thrown out right away, I think this system really would solve a lot of problems. That and actually investing in the TTC so it isn't completely ridiculous anymore.
