When Dale Kennett, asleep in a car, thought he was being attacked by a drunk man he panicked and hastily reversed out of a driveway.
But in the dead of night, with his windows fogged up and only one working headlight, the 54-year-old couldn't see that another man, Jason Young, was lying on the ground.
Kennett drove over the top of Mr Young and killed the 48-year-old at Hamilton, in Victoria's southwest, in March 2020.
