Worst place I drove through was when I took a wrong turn outside of Birmingham centre, ended up on an estate and thought I was going to get lynched by the taliban.
A good call would be Oldham, what a tip...
Kensington and Speke in Liverpool...wear a bullet proff vest!
The place i hate the most in the UK is Blackpool, what a s**t hole. A rip off Vegas wannabe, full of p**s heads, smack heads and knob heads. My ex loved the place..til she went there alone and someone tried to nick her bag!
