So if you ask me it is just as noticable as say a statue in the city centre.”
Exactly. In over 45 years of Who, it has never been suggested that the TARDIS is in any way 'unnoticeable'. Indeed, the number of times it was mentioned, stolen or confiscated in the classic series makes it pretty obvious this is not the case. No idea where that one came from...

The field extends to objects associated with the TARDIS, such as the keys used to open it. Perception filters can also be added to other objects, such as the fob watches used by the Doctor and the Master. The TARDIS also imparts a perception filter to a stone slab near a fountain in Cardiff during the events of "Boom Town", which Torchwood Three has attached to an elevator. The field does not work if the object it surrounds draws too much attention to itself, or if someone is specifically searching for the object in question. Those with even minor telepathic abilities are also immune. Martha Jones uses the one installed on her TARDIS Key to protect her from the Master's detection during the year he ruled the world. It would appear that those who have previously seen the TARDIS are not affected by the Perception filter, such as Sarah Jane Smith when she discovers it in School Reunion.”
There is no basis for this article at all. Wikipedia is not a great source for reliable information since anyone can add to it.
