Guys I really appreciate the feedback.
Just to answer some of the quotes on here:
Should I have let it go?
Yes and no. Yes if I hadn't an idea on the route of the bus to get his details. My determination in proceeding to get his details is due to several factors; one he cut me up without any consideration and halted the bus abruptley, two he attempted to ram the bus into me when requesting his details, and three, if the driver states to me that he didn't give a "f*ck", it made me more determined to report him.
Could I get his details after he cut me up before the accident?
Unfortunately not. When I was requesting his details I was attempting to take my gloves off and phone out and this when he was driving the bus towards me to run me out of the way. By the time I even got the phone out he'd already sped off towards Brixton. This is the reason I decided to cycle to a location where I'd get to video and record the details. Then the accident happened.
