What is the biggest menace?

Colleagues in my office were discussing the provision of statutory levels of bike parking for new build units in London, and commented that they wouldn't cycle in London because it was too dangerous, although one colleague noted the most risk was probably from other cyclists
!
So - what do you consider to be the most risky road user with which we have to contend?
EDIT: motorbikes and scooters added

I am not sure. You have no chance.
Second to that are taxi drivers if only because of the fools of themselves they make by whinging about cycling constantly, added to that, at least bus drivers mostly have vehicle handling skills, taxi drivers are the worst drivers on the road by far.

I'd say the opposite (within reason - you only notice the bad ones while ignoring the majority) - anyone on the roads that stands to make more money or indeed, keep their job by going faster is gonna be more tempted to cut corners and break the rules. I see more bad driving by 'professionals' in London than anyone else.
It's dog eat dog out there..which is why they're building the super highways...
In lieu of that, I just checked 'cars' because every single serious off or near-off I've had (with the exception of one white van driver and one bus) has been a private car or minicab

Yes. Both. Either.

Right, have added Private hires as a separate category, edit away...

you obviously haven't seen some of the cyclists round here!
Farmers are my pet hate and the most recent death of a cyclist I know involved a tractor.
Don't live far enough north to encounter deer, though I wouldn't like to collide with one running across the road.

Oh FFS right I'll add farm vehicles and their insane drivers

What makes you think so? Please explain.
Fair point - the geese in Hyde Park are a menace to society. Plus dogs on invisible leads on one side of the path & their owners on the other. Tricky

for london they are 50% of the deaths, have been as far back as i've bothered to check.
for the uk as a whole it's cars.
I rarely even on my jaunts into central London have much problems with buses, normally U turning taxies, agressive mini cabs and the occasional poor cycling, normally either drafting/halfwheeling/boxing in etc.
I think woosh and woosh sums that up!
I'm probably more concerned with a mid-to-serious injury. If it's time to go, and it's due to a lorry than perhaps so it is... On this basis my vote goes to dear pedestrians, addisonlee and motorcyclists. Favourite pedestrian move: start walking backwards on a zebra crossing having reached half-point (why oh why?).
We also need to look at the kind of cyclists who get into the sad statistics. Would an aggressive cyclist who stays in the middle of the road be less likely to be squashed by a lorry? I tend to think so. Do you?
I ticked Car, lots of examples of lots of tools but most incidents for me have been from impatient/selfish/inconsiderate d1cks in car.
