Just under a million (mainly younger) drivers have a telematic device installed in their vehicle to monitor and track how they are driving. The behavioural incentive is clear - safe driving helps to bring down the annual cost of car insurance which for those under 25 (and their parents) can be prohibitively expensive.

The price of an average car insurance policy has soared by almost 20% in the past year to nearly 850 pounds annually, by some estimates.

Could the telematic device become much more widespread in years to come. Telematics allows car insurance companies to base premium on how well you drive. Car insurance premiums have rocketed in recent years and insurance companies are essentially in the business of pooling risk. Here is a highly accurate piece of technology that could improve driving behaviour across a much wider section of the population.
