This week on Overdrive, David Brown and Paul Murrell (SeniorDriver.au) dig into what’s changing inside cars and on our roads — from the future of in-car radio and voice control to over-the-air updates that add features after purchase. They also unpack NZ’s roadside drug testing rollout, sidewalk delivery robots, the rise of Chinese brands in the UK, a Louis Chevrolet history detour, and a major expose on why dodgy traffic data can distort real-world decisions.
