Peter, I’m really sorry to read about your story, and I hope that your friend considers counselling. Any good health-care system will have such an option embedded into a treatment plan after such an incident. Sometimes people only realise the value of it a long time afterwards, it may take time.

I’m far more aware than I used to be of speed, and the impact this has on reactions to the unexpected. I try to read the situation in front of me where I can to give myself options where possible. We all see people taking risks on the roads, most if not all of us have taken the risks as well, and learnt from them. I know I have.
