"I'm thinking what saved me from getting run over was the lady appeared to be an experienced and cautious driver. I'm guessing she was driving defensively and saw what was about to happen and instinctively came to a stop as quickly as she could. Had it been a more aggressive driver there is a good chance I would not be typing this........."
This had to be a terrifying event (after you had a chance to think about it) for both you and the driver of the car. I've always been a defensive driver and given lots of space to pedestrians, children, stopped vehicles, cyclists, etc. I have noticed since I've gotten back into cycling that a lot of drivers don't give cyclists a lot of room. I was riding on a road with a 5 foot shoulder yesterday, and noticed that only about 1 in 3 cars moved over into their left/passing lane when passing me, even though no one was coming behind them. Fortunately for everyone your encounter was with a woman who acted responsibly. Incidentally, I got a hematoma from a fall (much less frightening than yours) about 4 weeks ago, and it still sticks out from my thigh about 1 1/2 inches and about the size of a grapefruit. The doctor said it will take 1 1/2 to 2 more months for the body to reabsorb it. Nearly all of the bruising has been reabsorbed, and while my wife has been concerned with it, the doctor didn't seem concerned in the least.
