Questions are being raised about a new mobile app which tracks, records and scores how people drive.
The insurance company Tower has launched, GoCarma, which monitors people's driving habits, from how they brake to how often they check their phone.
Tower says the app is a way for people to measure their driving ability and potentially lower their insurance excess.
However, critics warn the application intrudes on people's privacy and it's unclear who's really getting the benefits.
Business reporter Nicholas Pointon has the story.
