Gadget Man Richard Ayoade turns his attention to public transport, as Russell Howard joins him on the Tube to assess the effectiveness of gadgets designed to tackle poor air quality and extreme heat.

Richard also takes to the London skies in a cable car to check out mobile entertainment devices, before riding a commuter train with Adam Buxton to test portable cleaning and sanitising devices.

He also tries out a prototype for a driverless taxi with Adam that would make any taxi fearful of the future.
