Irregularity is typical of European city centers, because they grew 
up long before city planning was a big thing. Many American cities 
were laid out on a plain grid on essentially blank land, as opposed 
to growing up helter-skelter and being mapped later. The exceptions 
are where they were gridded over an existing set of Indian trails 
(for instance Packard Road and Plymouth and Pontiac Trail in Ann 
Arbor, which come in at odd angles to the imposed grid).
