The "idiot" who tore up a Dunedin sports field with their car does not understand the impact they have had, a rugby club chairman says.
In an incident on Tuesday night tyre tracks were spread across multiple playing fields at Bathgate Park, and the grass ripped up.
Southern Rugby Football Club chairman Blair Crawford said the damage to the field was frustrating.
"Some idiot who thinks it's a laugh doesn't realise how much it impacts everybody else," Crawford said.
