i'm very sure Birmingham is worse. never seen so many nutters retards in one place in my life, even had 2 non-fault accidents in less than 24 hours less than a mile apart in B'ham before!
also the only place where a woman sees you waiting in a queue of traffic behind her parking space and reverses out into the side of you anyway, even after i'd horned at her 
I drive in Birmingham every day, and to be honest, you are just forced to drive aggressively, rather than defensively, in order to get through in one piece.
Ive had 2 non faults as well, but in the space of 5 years. And to be honest, both were in Solihull not Birmingham.
