Mohamed Abbasher Fageer was driving to work on a dull and drizzling Sunday morning last December when a single lapse of concentration changed his life and many others, and ended that of a young doctor returning from her morning bike ride.

One minute he was rounding the corner from Mona Vale Road into Woodlands Avenue in Pymble, then there was a loud bang, and the next moment he was outside his car and hysterical.

Christopher Vanneste said there were no winners from the proceedings.

"I didn't see her," he cried.

Ann Formaz-Preston was lifeless on the road.
