Angry driver attacks cyclist OY62 OFC

This ones going to the police! This guy pulled into the green cyclist box on the approach to Pevensey Bay indicating that he was turning left so I gestured as if to say what are you doing this is a cyclist / motorcycle box to protect us from what you're about to do. He wound down the window and spat some abuse and then sped off turning left towards Beachlands. I gave him a cheeky wave (not anything more) and cycled on towards Eastbourne forgetting about the matter. He later passed me very close and drove down to Martello Road where he waited for me. I noticed that my go-pro was dead and this is when I got my phone out as I could see what was going to happen. There is no preceding footage as my go-pro battery had died. I took the video on my phone as I thought it would deter the driver from over reacting. With a bike between my legs and one of my feet still cleated into the pedals, what more could you expect me to do? This has been reported to the police and I will update this post later. A cheeky wave is just that, not a gesture in any way. I have no interest in getting involved with people like this as I am a grown up.
