Perils and ethics of new driverless cars Letters

I was disappointed that David Edmonds (Driverless Cars still need a moral compass. But what kind?, Opinion, 15 November) failed to credit one of our most brilliant British moral philosophers who developed the "trolley problem" as a way to abstract the reasoning behind ethical decision-making. Philippa Foot is rarely given her due even though these thought experiments are regularly cited in modern philosophy. Her inventiveness has helped inspire the next generation of philosophers to engage with the practical challenges of artificial intelligence. And we wonder why philosophy is dominated by men.
