No sympathy. You were in the middle of the road throughout the whole video which you would only do to provoke a reaction. Other cyclists passed you nearer the kerb. And with all those bloody cameras dangling from you and your bike you need a confrontation or your footage would be as dull as your life.
Seen this kid racing around llantrissant bypass. Some ugly looking dog thinking he's chocolate with a car full of fat lads. If he thinks he's pulling any lasses looking and driving like that then he needs to think again, though he may have a shot with the idiot in the snapback sat next to him. Slow the heck down or you won't even make it back to his place
So he cuts you up by entering an occupied cycle lane at 20 mph, then makes threats? Wow, what a big man. Was it a works van? Why did he stop? I wonder if he knows that leaving the scene of an accident could be very bad for him and/or the company he represents! Glad you're OK. Oh, and please video this individual just in case - it's a public place there's nothing he can do about it (aide from maybe make himself look an even bigger idiot I might imagine). He could have killed you through his stupidity - cyclists, keep an eye - and a video camera - handy ;))
Speaking personally. Seeing as the BM was just at the width restriction before you, I would have just let it go rather than make some sort of point.
On this point, a few years ago as reported in my local newspaper, the council put in one of these width restrictions. Later the local constabulary informed the council that it was a dangerous obstruction with the potential to force vehicles into a head on crash situation. It was very quickly removed.
Some say Stoyl came down the track and beat the stig, Alls I know is, He DID! That is the only true comment! Good driver, Pick him up Ferrari!
