WATCH: 'Buzz car' - this monster Ford Focus RS reads your emotions and shows the world how much you're enjoying the hot hatch

Ford has been working with neuroscientists and designers to create a customised Focus RS that's capable of reading the emotions of drivers.

The Focus RS, at Stratford Waterfront in London, displays its 'Buzz Moment' whereby exterior lights illuminate in tune to the driver's emotions behind the wheel.

Dr Harry Witchel, a professor of physiology explains that the "buzz car" is a special concept, customised to accommodate new technology.

The driver is connected to sensors and the data collected is displayed via coloured lights.
