I'd be wary of selection bias here.

Motorists have little to gain by reporting an accident in which the cyclist is at fault whereas the converse is not true. A cyclist might have a lot to gain for reporting an accident at which the motorist is at fault.

Serious injury aside, it is usually easier for a guilty cyclist to scarper after an incident since there are no identifying registration plates and the bicycle is more manoeuvreable in a tight space.

I cycle and I have to say that I see much more poor behaviour from cyclists than cars.

I'm trying to find the original document Westminster rather than reply on press report. That should give some insight into the methodology and how far any selection bias in reporting might apply. Unfortunately Westminster Council's website is more difficult to navigate that its streets!!

I suspect however the accidents concerned are those where the cyclist is injured. That sample would not include 'scrape and scarper' encounters where only property (car) is damaged.

My London experience is that there are bad behaviours on both sides.

The main offence by cyclists is blatant red light jumping. Mostly harmless but very bad news reputationally for all of us. Close passing other cyclists is another. Riding with earphones is the one that really gets my goat - hearing is just to important a cross check to eyesight to be impaired even by open backed phones.

The main offence by motor vehicles is amber/red light jumping. Barely anything stops on amber and most cycles see one or two cross the red. Buses and taxis are amongst worst offenders. Other bug bears are close passing, unnecessary overtakes (feet befroe a red light for example) and the 'left hook' turn.

My biggest bugbear with cyclists, is hoping from the pavement onto the road without warning. Depending on the angle of entry it can look like they're trying to cross the road.

In Cambridge last week a female twazzock was just in front of me to the left in a designated cycle lane. Without looking she rode out into the road right in front of me, without looking, to pass 2 cyclists in front of herself. As a result she did find out the sound of my car horn. I have thought of having a windscreen washer nozzle pointing at the pavement for just this kind opf incident. Only a thought!

You have to, to get around the parked cars!
