A tiny puck-shaped gadget promising to warn drivers about speed cameras and road hazards – I tested the OOONO Co-Driver NO2 to see if it really works

Modern cars are crammed with technology. Screens everywhere, navigation systems that want to talk to you constantly, lane-keeping assistants tugging at the wheel, and warning chimes that make you feel like you’re piloting a passenger jet rather than driving to Tesco. And yet, despite all that technology, there is still one thing many drivers worry about: speed cameras. Enter the OOONO Co-Driver NO2, a small Scandinavian gadget that promises to act like a silent passenger in your car – warning you about speed cameras, road hazards, and traffic issues ahead without distracting you with yet another screen. It’s an interesting idea. But does it actually work? Let’s give it a go!
