The latest video in our Near Miss of the Day series starts with a driver overtaking a couple of cyclists dangerously - and ends with the motorist shortly afterwards slamming his brakes on without warning, causing one of the riders to crash.
It was filmed in Dorney, Buckinghamshire yesterday by road.cc reader Lyndon (and is the second video from him we have featured this week), who told us: "I had an encounter today which I'd consider a hit and run.
"It was a nice day so a friend and I decided to head down to Windsor, Berkshire. Just outside of Dorney Lake, a white BMW followed passed very closely.
"I knew there was a busy junction ahead and figured I'd catch the driver up at the junction and tell them to be more considerate.
"When I got near the the car, he saw me and brake checked me, and I went into the back of him. If you play the video slowly, you can see him looking in his wing mirror as I am falling down.
"I am completely dumbfounded as not only did the collision make a loud bang, that the passenger in the vehicle did not encourage him to stop at the scene.
"It's a sad state of affairs when someone knocks a cyclist down and leaves them in the road.
"I have sent the footage to the police, full files of front and rear footage where the faces of the driver and passenger are visible. I can only hope Thames Valley Police will prosecute him," he added.
"I do not understand how someone who behaves this way is permitted to use a vehicle on public roads."
Over the years road.cc has reported on literally hundreds of close passes and near misses involving badly driven vehicles from every corner of the country – so many, in fact, that we’ve decided to turn the phenomenon into a regular feature on the site. One day hopefully we will run out of close passes and near misses to report on, but until that happy day arrives, Near Miss of the Day will keep rolling on.
If you’ve caught on camera a close encounter of the uncomfortable kind with another road user that you’d like to share with the wider cycling community please send it to us at info [at] road.cc or send us a message via the road.cc Facebook page.
If the video is on YouTube, please send us a link, if not we can add any footage you supply to our YouTube channel as an unlisted video (so it won't show up on searches).
Please also let us know whether you contacted the police and if so what their reaction was, as well as the reaction of the vehicle operator if it was a bus, lorry or van with company markings etc.
