Aviva promises 20% car insurance cut for driving App subscribers

Aviva has developed an App for Android phones which measures driving habits and can result in a 20% car insurance discount for those the App suggests are particularly safe.

The RateMyDrive App measures acceleration, braking and cornering but requires no "black box" to be fitted to the car – the standard way of measuring driving habits. It records a driver's technique over 200 miles and then comes up with an overall score.
