"This incident could so easily have ended in tragedy and we are pleased that no-one was hurt."
The footage emerged earlier this week after being posted on social media.
Scott said he and his friends got bored on Tuesday afternoon and wanted a challenge with a cart they had bought off Trade Me a few weeks ago.
"So the boys said they'd buy a box if I did the Kaimais," Scott told Bay of Plenty Times.
A video shows Scott shirtless and travelling at speed down the west side of the State Highway 29 range, being filmed by someone travelling in a car behind. At times the cart ventures across double lines and heavy freight trucks can be seen travelling in the opposite direction.
"I got a few toots and funny looks. I know I swerved out into the other lane but I could clearly see there was no one coming."
One of Scott's friends panned a camera to film a line of traffic stuck travelling behind them before panning back to record the luge rider.
Police earlier labelled the stunt "brainless" but Scott has said he might do it again on the Bombay hills, South Of Auckland.
Scott declined to comment on the fine when contacted today by Bay of Plenty Times
