The end for the "I'm five minutes away" lie?

A smartphone app from has recently received an update which may leave a lot of cabbies red faced. 

The app, which works on Android, iOS and BlackBerry, now offers the user driver information, such as a picture, previous user ratings and contact details. 
Not only that, the GetTaxi update also includes real-time tracking so you can see exactly where your taxi is. Looks like cabbies can no longer pluck figures out of the air. 
These advancements are supposed to make the service a lot quicker, smoother and safer but Downtime can’t get one thing out of our mind. 
What’s to stop a driver who gets really bad ratings just changing their name and the way they look?
Or are we being paranoid?
