Scary screaming cycling lady (the London Banshee)

!!!!! It's defiantly the one I've seen / heard doing the deep growling on Jamaica road. This can mean only one thing. It's a cult.

Def the Greenwich/Depford lady - I reconise the assertive arm signaling (she can go down the middle of the road for many yards like that) Also a fair bit of upper body movement.Tommy you didn't mention whether she made any sounds...did you?
