Well I had a spare hour so I did a bit of searching, from what I can work out it is south London. I also think I found the guy http://www.myspace.com/dimz786 so I thought what the he'll and emailed the London MET....Dear MET Police, I came across this YouTube video http://www.youtube.com/watch?v=uIDMIOpyeEg&feature=player_embedded which looks to be one of several which show extremely dangerous driving. I'm not from the area, but I think its south London. I thought you might be interested in it as there are several points at which you can also read number plates. Sorry if this is wasting your time, I didn't feel it warranted a 101 call, and its very difficult to pass on this kind of information on the phone.
Enjoy
Richard
