Westfield Group, one of the largest shopping centre operators in the world, has launched a find-my-car iPhone app. The system uses a series of license plate reading cameras dotted throughout their multi-level car parks. Westfield said police could also use it to find stolen or unregistered vehicles. (Hello, slippery slope.)

I take public transport, so people track me with my purchased tickets. In Singapore with proximity stored value cards, this is even easier. As a kid I went all the way out to Jurong East and Pasir Ris just to muddy and confuse their "downtown expat" profile of me. I was a wild, out of control teen ;).

As to this Westfield story, it rubs me the wrong way but I suppose it was only inevitable.
