Driverless Roborace car speeds around Donington
   

A prototype race car testing self-driving tech for the forthcoming Roborace contest has made its public debut at Donington Park`s circuit.

The Devbot only completed one lap round the course without a human in control.

But the London-based investment fund behind the initiative - Kinetik - hopes to launch a competition featuring autonomous electric-powered cars racing against each other over the coming months.
