Given that it takes ~four seconds to pair my stationary iPad with my stationary JamBox, I'm skeptical of this claim. I once worked on a project that involved using tick data collected from the thousands of induction loops embedded in California freeways. Despite the data being somewhat noisy and error-prone, it was not difficult to more or less accurately infer traffic flow from these counts. I had always assumed that this is how they produced those estimates, but this was about 6 years ago.
