Motorist who chased cyclist through Barnsley after road rage incident says she doesn't know why he rammed her car door

could also be:

cyclist cut-up, doored and chased across town by road-rage motorist

another good reason to have cameras if that was the case. often an incompetent motorist will describe perfectly legal cycling such as filtering and primary position as 'weaving all over the road'.

I'd be annoyed if a driver overtook me to get to a red light whilst swinging in close to the curb to prevent me from filtering.

However, I'd usually go for a passive aggressive overtake, position my bike right in front of the car and then when the lights turn green, slowly pull away and maybe experience difficulty clipping in.

Dozy bint extreme close passes cyclist, pushing him over the edge.  He angrily thumps her car, causing no damage, and gives her an earful.  So she accelerates ahead, pulls into a layby, puts her most powerful Karen face on and has a go.  Cyclist, pissed off with yet another clown who doesn't know how to drive safely, loses his rag, chucks his bike at the car, tells her to get in the sea, and rides off.  Karen gives chase.  She loses him, but showing deep concern for her "terrified" daughter, finds him again and gives chase, raising the possibility of another "terrifying" confrontation and increased Facebook points.

Local newspaper writes clickbait bullshit article from Karen's point of view.  Cyclist remains at home, wondering what the hell it will take to get people to drive responsibily.

As others have said, cyclists just don't randomly attack drivers without severe provocation, and her description of the incident is from her entirely oblivious windscreen perspective.

A possible scenario is that the lights were red, but she overtook the cyclist anyway and forced him to do an emergency stop to avoid being pushed off by the side of her car.  That would certainly get me wound up enough to do something like that.

I don't have any idea what she might have done to him to push him over the edge, but it was probably something.  Maybe even putting his health and/or life in danger.  A lot of motorist are completely oblivious to the danger and risk they are causing us, cocooned as they are in the big metal box.

It's the "They like to weave around traffic, don't they?" comment that gets me, surely the act of "properly" overtaking (giving enough room of course) and then pulling in right up to the kerb (seems strange...) involves a amount of weaving about itself, doesn't it?

And of course the pointlessness of overtaking ("properly") when approaching a red light....

See, I don't condone any attack on anybody who had done nothing to deserve it but I wished we had footage of the start as she apparently went past him to stop at the traffic lights to turn left. The junction road is very narrow for two cars side by side so how much room did she give when she went past initially?

It would have to be a really psychotic cyclist (and there are probably some) who would have been upset at the small amount of space if that is the only issue here. 

I also don't like her comment "They like to weave around traffic don't they". No they like to filter when there is space and lots of traffic ahead that is stationary. 

Somehow I don't believe we're being given the full picture by this person.

I've never heard of a cyclist randomly attacking a car in this way but a person might be enraged enough to do so, rightly or wrongly, having felt their life threatened by bad or dangerous driving.

She admits driving close to the kerb to prevent him filtering but then accuses them(?) of weaving. A case of someone putting their Myway Code ahead of the Highway Code? Could have allowing space to filter, as per the Highway Code, have prevented this?

She claims he threw his bike from 6' away then rode away. They're some pretty tough wheels that you'd risk doing that to and who does that with a decent bike anyway (apart from the pros)?

Then as she follows him (far too close but she may be following her Myway Code on safe distancing) who's taking photos of him? Maybe mobile phone use whilst driving is where this all started.
