Anyway all aside, well done on stopping and being helpful.
As a contrast, when I was hit earlier this year (driver was clearly at fault, turned from other side of the road onto my right of way), the driver had no compassion at all, as I was lying on the road, shouting at me saying it was my fault.
Luckily 20 school kids witnessed it and shouted back at her, as she would have hit them if not me first. Driver admitted liability by the end of the day and all paid out quickly.
