Roborace is still pursuing its driverless race-car dream

Clearly, Roborace doesn't believe in bad luck. Last week, on Friday the 13th, the company chose to run its self-driving Robocar in front of a feverish crowd at England's Goodwood Festival of Speed. It was only the second time the team had demonstrated its futuristic vehicle publicly, following an unassisted lap in Paris roughly 13 months ago. There was no room for error. The absence of a human cockpit gives the car an unusually low profile.
