The Children in Need chairman was caught on CCTV smashing a female cyclist off her bike and sending her flying into the road.
Terry Duddy, 69, was announced as the chair of BBC Children in Need just 11 days ago, but has since resigned after his driving conviction.
CCTV footage of the collision in June, shared by Thames Valley Police, shows Duddy’s black BMW turn right, cutting in front of a cyclist, believed to be in her 50s.
The SUV then smashes into the cyclist, sending her flying into the air before she lands back on the hard concrete.
Fellow cyclists, who were following shortly behind the woman, rushed over to help her as she lay on the ground.
The former Children in Need boss was handed an 18-month suspended sentence last Thursday. He was also ordered to carry out 200 hours of unpaid work.
The 69-year-old confessed to the BBC regarding the incident on Tuesday and told them he would have to step down from his role as chair due to the fallout.
The broadcaster’s board agreed. James Fairclough, who has been a trustee for the charity, took on the role with immediate effect.

Duddy had also been a boss at some major UK retailers, including Argos. He is also the chair of London Marathon Events as well as the welfare charity Catch22.
A Catch22 spokesperson said: ‘We were notified yesterday by our Chair, Terry Duddy, of his conviction for careless driving causing serious injury.
‘We are investigating the implications of this for his role at Catch22 and will provide a further update once this is complete.’
It comes amid a series of resignations at the BBC in recent weeks, with the broadcaster’s director-general Tim Davie stepping down.
The corporation’s CEO of News, Deborah Turness, also resigned amid a row over the doctoring of a Donald Trump speech for a Panorama episode.
In a statement, Mr Davie said: ‘There have been some mistakes made and as director general I have to take ultimate responsibility.’
