On the insurance issue, I know of many cyclists who during the fight for compensation toward damage to bikes et al have used camera footage to prove the driver was completely in the wrong. In one case the driver just cut right in front of the cyclist who was quite legally cycling down the road. Bike was a write-off and a few broken bones yet even though the written reports were damning they were trying to fight the cyclist's claim....until they saw the footage whereby they folded like a paper staircase 
Good idea. But sadly a lot of cyclists dont act in a legal maner by pulling some of the stunts they do (Especially the red light dash)
I tend to give cyclists as much space as I can, and even more to some of the moronic motorists I have come accross over the years.
Having been knocked off my bike (Through no fault of my own - I was stationary at the time) as kid (and only being allowed on the road because I had passed my cycling proficiency test) I am well are how dangerous it is for cyclists. I am still of the opinion that cyclists and horse riders some have some entitlement on some sort to be on some of the classes of roads we have today.
I am not sure if there is any sort of legislation in place, but if not there should be. Obviously any one passing any part of a driving licence has been trained to understand the roads.
But kids of any age can jump on a bike and ride down the majority of the roads, and maybe to a degree is the same for horse riders. Insurance ought to be compulsary for all road users, anyone could end up in an accident, I once had a horse stampede over my Jag going into town one day, 10 year old girl was riding, something spooked it at a junction, the girl wasnt experienced enough to cope. She took it with out the owner knowing she was on roads with it. But she could have got seriously injured
Most bikers are responsible and experienced and understand the driving habits of people arround them as Gaffers does, it's that odd percentage, the push nike couriers, (Certain) teenagers that dont respect the road or people on it.
Gaffers, please dont take me the wrong way, I am actually on your side, but if we could repect and treat others as equals on the road then maybe there would not be any accidents, sadly there is, it's that that is not equal, as motorits, we have Tax. test, insurance and a licence to be there, a cyclist needs none of these.
