Thing is this was introduced to the world in 2004 by a clever guy which I've forgotten his name i will find it he's German but he suggested this idea.

All cars come manufactured with a CPU which can be scanned by police each unique to a car.

The CPU is updated via 3G and if you for example purchase insurance the car is automatically updated via the CPU and the car when scanned shows a valid policy from start to finish, this also applies when cancelling it's automatically removed from the vehicle making scans or stop checks more efficient telling the police there and then if insurance is valid.

Same applies for Tax If these cars do not show up with either upon scan the police can stop the car call the centre of operations with this CPU software and check on a mirrored server which data is sent immediately by insurance or DVLA making it a there and then fine and car being taken off the road.

Instead of this new law in which, involves the injections of cash which is temporary but will make a significant profit from interest for insurance companies before the consumer changes his policy again.

example

bill pays £400 for his 6 months insurance he wants to use his car for 2 weeks.

week 1 the payment has made from interest 0.004% interest
week 2 the payment has made interest .0.005% interest

now times that by 6 million drivers doing the same thing.

it's a scam however we could see a fixed lower price for all policy users as the margin to lending and borrowing will be covered by the interest in which they can make.
