When the car pulled into a driveway, he checked its details on his smart device, learning it was stolen and firearms were likely to be on board.
He said he called for back-up and another officer carrying firearms arrived.
"We tooled up ... put on bullet proof vests and picked up firearms," he said.
"While we were doing that, I noticed the black car coming back, I put my hand up to stop it but it just went past."
Mr Hubner told prosecutor Ngaroma Tahana he was 100 per cent sure the driver was Daly with whom he'd had dealings over demerit points.
Questioned by Daly's lawyer, Maria Pecotic, he insisted he had an unobstructed view of the driver despite the car's tinted windows and its speed.
Earlier, the jury was read a series of text messages to and from the woman who was allegedly injured by a sex toy during a tryst on a boat with the alleged main kidnap victim, a wealthy businessman.
One sent by her to her partner, Dwyer, said: "I don't want to be here [hospital] alone. I've been to the operating room, lost too much blood, I want to go home."
A text to her from the businessman read: "Very sorry for making you sick, I will have to take you on holiday trip sometime to make you better."
