Vehicle insurance companies can charge what they like, since we all must be insured to drive. Today’s invention is an opportunity for one of them to break ranks and make the costs fit the risk for each customer.
It consists of an in-vehicle computer which calculates the journey risk profile each time you turn the key in the ignition, based on some stored data and by answering a few extra questions.

It seems that the time of day affects the chance of an accident, as does the weather forecast, driver details and the maintenance history of the vehicle. This information would be stored in the system.
Specifying your planned route on Google maps, via an onboard screen, would allow all this information to be mashed up and a real-time quote generated. This would be authorised to be paid, using one’s stored account details, before the journey began.
