Cycling accidents

I wrote the other week:

I'm a bit concerned that I seem to be coming off my bike so much; I don't get the impression from other cyclists that they have so many accidents. Some of them are of course my fault [...], and some bad luck [...], but still.

I'm aware that my reaction to this might be coloured by having come off my bike twice this year, and twice in rapid succession one and a half gosh, two and a half years ago, so I thought I ought to quantify that I'm talking about, to see if I'm being unreasonable.

And the result (colour-coded, so you might need to click through to the post if it appears in your f-list on an unhelpfully-coloured background):

Date	Cause	My fault?	Other person involved/at fault?	Pure Bad luck?	Injuries
1981ish	Used front brakes only on reaching foot of hill	✓	✗	✗	Skin loss and bruises
1988ish	Lost control and fell off; possibly for same reason as Nov. 2000 incident	✗	✗	✓	Skin loss and bruises
1989ish	bluepork's friend tried to pass his skateboard between my wheels as I cycled past	✗	✓	✗	Skin loss and bruises
1998	Went around corner too fast at bottom of hill	✓	✗	✗	Grass stains only: controlled landing
May 2000	Went around corner too fast at bottom of hill (I was a slow learner due to escaping unharmed the previous time!)	✓	✗	✗	Grass stains only: controlled landing
November 2000	Foot slipped off pedal, and didn't have enough centrifugal force to keep upright	✗	✗	✓	Tore fingernail out
January? 2002	Pedestrian stepped out onto the road in front of me	✗	✓	✗	None, thanks to bike helmet
March 2003	Hit-and-run driver turned left immediately in front of me	✗	✓	✗	Skin loss and bruises
March 2005	Lost traction on snow	✓ (for cycling on snow)	✗	✗	Only a minor graze, because ground covered in snow
March 2006	Driver performed U-turn into my path	?	✓/?	✗	Minor grazes, but derailleur sheared off
August 2007	Handlebars snagged by street cleaner's bag blown out by the wind	✗	✓/✗	✓	None, thanks to bike helmet, but derailleur needed adjustment
January 2011	Front mudguard hit wheel	✓ (for not recognising bike fault)	✗	?	Skin loss and bruises
January 2011	Front mudguard hit wheel	✓ (for not recognising bike fault)	✗	?	Skin loss and bruises
December 2012	Came off on black ice while stopping to help other cyclist who'd done same	✗	✗ (sort of!)	?	Mild skin loss and mild bruising
June 2013	Knocked off by motorist turning across my path	✗	✓	✗	Skin loss and bruises

And the conclusion? Well, what do you think; do you think I am coming off my bike too much (compared to, for instance, yourself)^*, or just unlucky, or a risk-prone road user?

* Given that the above covers several hundred miles as a child/teenager, a gap when I wasn't cycling between 1989 and 1996, about 5000 miles in Edinburgh between 1996 and 2000, and over 21,000 miles in London since then.
