Scary screaming cycling lady (the London Banshee)

sadly it wasn't DJ, unless DJ is a 6ft 2 skinny cockney/Essex lad who cyles about with a pair of horns protruding from the vents in his helmet, noisily venting spleen at the most minor of potential traffic violations.

Have seen this guy in/around Putney, shouting incredibly loudly at pretty much any car nearby. I can't say I could tell what the problems were with the various drivers he was berating, he looked like he just likes shouting at cars and has mental problems. Cycles pretty damn fast though.
