Police said the tourist had moved to the right and moved back left in a manoeuvre that did not amount to dangerous driving.
The driver suffered bruising to his eye, his female passenger was shaken and police are seeking their assailant.
This week, in a separate case, a Dunedin man who took car keys from a tourist on the Otago Peninsula was found not to hold a valid New Zealand driver's licence.
Robert Penman made national headlines for his stance against a foreign driver on Highcliff Rd, on the Otago Peninsula.
He stands by his actions but surely a prerequisite for carrying out these sort of vigilante acts would be having your own house in order first.
The problem with vigilantism is that it is only a matter of time before someone, emboldened with a sense of righteousness and a mistaken belief that they can impinge on the rights of others, takes it too far.
People who see dangerous driving should confine their actions to a *555 call to the police unless confronted with an immediate life-and-death situation.
