Drama as car rolls down Auckland's Queen Street

People waiting at a central Auckland bus stop had to dive out of the way of a driverless car as it rolled down Queen St and smashed into a power pole.

The drama unfolded about 11am when a white car turned left onto Queen St from the Symonds St end of Karangahape Rd.

A black vehicle travelling straight on K'Rd then allegedly ran a red light and crashed into the white car at the top of the steep hill, causing minor damage.

Acting Sergeant Luke Dodson said the driver of the white car got out to assess the damage, leaving his vehicle in neutral with the handbrake off.

Meanwhile, the driver of the black vehicle reversed and pulled over to the side of the road.

"That's taken any kind of pressure off the white car and caused it to roll. The driver of the white car then chased it down the hill and it's hit a pole," he said.

The vehicle rolled about 30 metres.

Brad Fisher, who works at a nearby electronics store, said there were about 12 people at a nearby bus stop who had to jump out of the way of the rogue vehicle.

"People were scattering from their seats at the bus stop and jumping out of the way. It was going pretty quick on its own momentum," he said.

"It could have hit people, it could have so easily."

Acting Sergeant Dodson said it had not yet been decided whether charges would be laid.

"It could have been extremely serious. It is a public holiday and there were quite a few people around - families, kids, prams - so it could have been much worse."
