The BBC Radio 2 presenter posted the footage, filmed from his bike-mounted camera, on Facebook and Twitter on Monday.
It shows a black vehicle, in the lane next to keen cyclist Vine, which suddenly indicates and pulls over to the left in front of him. The broadcaster can be heard frantically beeping his horn and then crying: “Waah, wow!”
Vine, 51, has previously posted similar videos of motorists he claims are putting him in danger on his commute to the BBC studios.
One motorist who Vine filmed hurling abuse at him was put on trial at Hammersmith magistrates court and convicted of driving without reasonable consideration for other road users, and using threatening, abusive or insulting words or behaviour in February.
His latest video has been watched over 8,000 times on Facebook, where he described it as “another day in paradise”. But on Twitter, having read some accusatory comments, he said: “Oh, apparently I was to blame for this.”
Commenters have been divided as to who is in the wrong in the clip. One Twitter user, Michael D, said: “I think 50/50. Van was indicating and potentially you were in his blind spot. Anticipation due on both parts.”
Another added: “Learn to read the road and problems like this will become less frequent.”
