I haven't seen them as yet as I was on holiday when they did my town. 
Given the accuracy of GPS and if they were moving all of the time I 
can't see that wifi location will be all that accurate. They seem to 
have taken pictures every 12 metres on the estate and according to my 
neighbour they stopped several times however he didn't say whether this 
was prior to turning into other roads or not. Several roads were missed 
although they effectively circumnavigated those areas by using other roads.
