An Otago farm manager who deliberately destroyed several road signs could have caused catastrophe with his "idiotic driving", a judge says.
Jaime Lee Gaastra Pickens, 29, was showing off to his passengers when he embarked on the late-night rampage, the Dunedin District Court heard this week.
"He was with younger people, he was carried away and behaved in a juvenile fashion," counsel Alex Bligh said.
"He completely admits this is absolutely stupid behaviour."
Pickens was driving the Toyota ute, equipped with a large bull bar, on October 24 in Fennesy Rd when the destructive joyride began.
