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.
Born in Scotland, Simon moved to London aged seven and now lives in the Oxfordshire Cotswolds with his miniature schnauzer, Elodie. He fell in love with cycling one Saturday morning in 1994 while living in Italy when Milan-San Remo went past his front door. A daily cycle commuter in London back before riding to work started to boom, he's been news editor at road.cc since 2009. Handily for work, he speaks French and Italian. He doesn't get to ride his Colnago as often as he'd like, and freely admits he's much more adept at cooking than fettling with bikes.
