Re: I don't think this does as much as people think

It depends - there's clearly an algorithm that is working it out based on number of phones in a given area and type of road. 99 phones down a country lane = 99 cars all moving slowly so probably traffic. 99 phones down a motorway with hundreds of cars also in the same spot moving quickly - less probable traffic (although maybe shows one lane closed? Remember GPS isn't that accurate).
