A driver who inhaled laughing gas and killed a woman while speeding in a Mercedes has been jailed for five years.
Washe Manyatelo, 24, struck Annette Dixon, 70, in August 2023 while she was crossing the road with her walking frame in Edinburgh.
Mayatelo had been at a party the night before, had not slept and told friends he "felt fine to drive". He admitted causing her death by dangerous driving.
Sentencing him at the High Court in Edinburgh, judge Lady Ross said: "That arrogant self-assessment of your condition was woefully wrong."
She added: "This was a lady in her later years who was much loved by her family.
"They were close to her and that she is missed terribly."
Lady Ross also pointed out the car was borrowed and had dangerous defects that meant it would have failed an MOT test.
