I learned to drive in Hammersmith, so I thought I knew about terrible driving. At least London is predictably unpredictable! Birmingham is like a different planet! I think part of the problem is that the traffic moves slightly faster in Birmingham with a lot of dual carriageway and multi lane roundabouts right in the city centre which creates some... interesting incidents! At the weekend there is always some very fast German metal being driven very irresponsibly. I have to lay the blame on the city planners a bit though, the A38 tunnels do bring out the inner child/hooligan in even the best drivers. It’s basically like Midnight Club Racing in real life.
If you think driving is bad in Brum, try cycling!!
