Perhaps they were done from very earlier courier data, where the track points 
were much less dense, and their error margins weren't so apparent?  (Are 
their GPS units set to some 300-foot or 10-second tracklog interval?)

Look at anywhere in central london, the spread of trackpoints from a road is 
significantly larger than the distance between roads, so the trackpoint data 
just merges into a "mist" with slightly denser areas marking roads.  (I think 
I said as much on [[Talk:Central_London]])

If people bring GPS's to the Covent Garden meeting, we should be able to sort 
out a lot of problems in the central area.  There are already some 
high-detail tracks visible, meaning that people are starting to visit with 
better equipment.
