So how would you run a whole country without oil? That’s the question that sort of hit me in the middle of a Davos afternoon about four years ago. It never left my brain. And I started playing with it more like a puzzle. The original thought I had: this must be ethanol. So I […]

Translator: Robin Noel Reviewer: Denise RQ I’m going to talk about motor sports, in particular about racing.

How do self-driving cars “see”? – Sajan Saini
It’s late, pitch dark, and a self-driving car winds down a narrow country road. Suddenly, three hazards appear at the same time. What happens next?
