And wouldn't this same information be available in the UK from all those 
Trafficmaster cameras?

I'm prepared to believe that the TomTom data doesn't overtly identify 
individual cars, they could be sending the police tracking data based on 
a token for each car, although you could still build up a picture like 
those iPhone maps we saw last week, and know where the car was parked at
