Nice screen shot!

It may not be as one sided as you think though, although I admit the
grid-iron does figure more strongly in the older town centres. Look at all
those little cul-de-sacs in the newer residential areas. They are
effectively linear rather than grid and because of all the modern curved
roads there are loads of nodes. From all the cycling I have done up and down
this area I can say that there have been a lot more cul-de-sacs than grids. 

These little quiet cul-de-sacs should also carry an OSM warning about
getting funny looks when slowly riding a bike down the middle of the road in
a florescent cycling jacket. "You can't get out of here mate/love/dear"
seems to be the general response :)
