Broadcaster Jeremy Vine has tweeted a video showing the moment a motorcycle rider whizzed past - while riding on a cycle path.
The BBC presenter often posts footage recorded on his bike commutes to the social network - including one that earlier this year helped secure the conviction of a motorist following a road rage incident.
However, the video he uploaded at lunchtime today was taken from the passenger seat of a car that Vine was travelling in.

The engine of the off-road bike can clearly be heard as the rider approaches from behind and then, as he shoots off into the distance, a puff of smoke is emitted from the exhaust.
"Unbelievable" is Vine's verdict at the end of the video.
