A couple of points
1. How much more expensive would a traffic management system that records the data be, than a system that simply records it? If, as I suspect, it wouldn't be that much, then this could have serious implications.
2. Have they thought of the obvious counter measure? An app that accesses thousands of websites to overload the system. Which of course will then appear as a virus either spamming the records or deliberately going to dodgy websites without the user knowing.
