A dad drove his son 170 miles to west Wales before crashing twice in the space of a few minutes and then trying to drag a terrified woman from her car at a roundabout.
When questioned by police, Stephen Skidmore said he thought he had been poisoned, and that his life was in danger. A court heard there was no obvious reason for his bizarre behaviour but it may have been linked to a "very bad reaction" to cannabis he had taken a few days earlier.
Swansea Crown Court heard the 66-year-old driver Skidmore assaulted - who had been driving her off-duty police officer daughter at the time - had been left feeling "really shaken up and sick" by the shocking events of the day.
