Matthew Wall:

But are they also becoming spies in our drives?
 As they record almost every aspect of our journeys and driving behaviour, interacting with our smartphone apps and sat-nav systems, who will own all the data they generate, how will it be used, and will our privacy inevitably be compromised?
 Telematics “black boxes” from insurance companies and related smartphone apps can already measure how aggressively we accelerate and the G-forces we generate hurtling too fast round corners.
 This monitoring technology is even becoming sophisticated enough to recognise different drivers based on their signature driving styles.
 According to the British Insurance Brokers’ Association (Biba), about 300,000 cars are fitted with these dashboard nannies. While that number may seem tiny compared to the 23 million cars on UK roads, there are many in the industry who think such technology will become standard in the next five to 10 years.
