A man caught on camera riding on a car's roof was doing the same "stupid" act that has killed two people in the Bay of Plenty in the past 10 years, says the Bay's road policing manager.
The car surfer and his driver were snapped by a motorist who followed them along Marine Parade last week.
In the photo a man is seen lying face-down on the roof of a red Mazda Familia, leaning his head over the driver's window with his feet in the air.
Police yesterday launched an investigation into the incident.
Western Bay of Plenty road policing manager Senior Sergeant Ian Campion said the behaviour was "just downright dangerous".
