He remained there for some time in a critical condition but sadly died from his injuries on September 19.
Detectives investigating the fatal collision have released an image of another cyclist they want to identify and speak with.
Officers believe this man interacted with the Tesla motorist shortly before it was involved in a collision with a minicab and the victim’s bicycle.
The Tesla owner, 44, was arrested on suspicion of dangerous driving.
He was taken into police custody and is currently released under investigation pending further enquiries.
The private hire vehicle driver sustained minor injuries.
Detective Constable Phil Stokes of the Metropolitan Police’s Serious Collision Investigation Unit said: “We believe that the cyclist pictured can assist with our investigation and may have vital information.
“If you know him, or if you are him, please do get in touch.”
A police spokesman said deceased cyclist’s family is aware and continue to be supported by specialist officers.
Anyone with information or dashcam footage relating to this incident is asked to call police on 101, or Tweet @MetCC quoting 6021/14Aug.
