In assessing the merits of driverless taxis (Driverless taxis from Waymo will be on London’s roads next year, US firm announces, 15 October), passengers should consider the cautions presented in Christian Wolmar’s book Driverless Cars: On a Road to Nowhere. Adherence to Isaac Asimov’s first law of robotics (“A robot may not injure a human being”) requires the taxi to stop if a person steps in front of it. Highway robbery or worse may be facilitated.
