A taxi driver acted in a psychotic manor toward me. Cannon St -> Tooly street

having said that, when the car hit me from behind at the junction and then tried to drive off, the police did ask me to put the phone on speaker phone so they could record the woman refusing to stop or give her details and the sound of her driving her car into me to try and force me out of her way.

so making the call did not make her see sense until the police told her by the speakerphone to stop, wait for them and that she had to exchange details

others have tried to take my phone off me when I have called the police

ideally you can get the pictures at a safe distance

so using a phone is not certain to work but it is worth thinking about

Just for future reference did you call 999 or the met police 0207 515 1212 number? Practical solutions above btw.
