RFID Passive Tags Track Cars
A South African company, iPico Holdings, "has developed and tested RFID passive tags and readers that can be used to monitor vehicles at a read distance of 17 feet traveling at speeds of 160 mph," according to this article from RFID Journal.

The tags are attached to the windshield inside the cars while the readers are placed on the roadside or on bridges. When an equipped car passes in front a reader, at a speed not exceeding 250 kph, the unique 64-bit ID of the tag is read. The readers, which cost about US$1,000, can detect up to 7,200 vehicles per minute (a pretty busy road, isn't?). The tags cost currently 60 cents each -- for an order of 5 million tags.

The technology will be used to control traffic and speed, but also will enable immediate traffic ticketing or toll collection. You'll find selected excerpts in this overview.
