I'm just trying to help so I hope it does not come across as prickish, but you are at fault. Was a liability investigator for 5 years before I finished up my ME degree so I do have some training and experience. You are fighting a losing battle uphill.
Was this in a parking lot or something? 10mph is a pretty slow speed limit.
Here's the deal...
neg #1) She had the right of way. (BIG)
neg #2) You had the greater duty of care in making a turn.
neg #3) damage location (if it was in the very back of the vehicle, may have more of a point) Also, I know it's only one picture, but the damage does not look too bad considering how you were hit.
neg #4) no witnesses
neg #5) you admitted to seeing her. The law says you have to be sure coast is clear before turning. Conversely, if you had admitted you did not see her you would be equally screwed...
pos #1) She may have been speeding, however it's hard to prove how much. Might want to get pics of her car if they support your case.
pos #2) Posted speed is 10 mph, suggesting that authorities know it is a bad intersection (that's how I would fight it)
At these speeds, the differences between 10 and 25 mph imo are not enough to put her more than 50% at fault. If she was doing 60mph, then probably.
Also, I've seen airbags going off when I would have thought it was impossible. They are designed to go off on full frontal impact with a stationary object (barrier) at just under 15 mph. However, I have seen them going off hitting stuff in the road with the undercarriage and pretty minor damage. Airbag systems measure deceleration, so if it senses one part of the car decelerating differently than other parts, it deploys. A vehicle decelerating, accelerating, spinning, etc can screw with the numbers.
If there was any obstructions to your view, it could be to your advantage.
Were you or was she cited? Put at fault on the accident report? How's your driving record and age? These could be to your advantage.
To argue it, I would try to argue the speed limit being necessary in the first place and other pro's you might have.
