Oh the humanity! According to the results of a recent psychological study on possible human reactions to autonomous cars, the subjects were four times as likely to trust a self-driving car with a human name and voice. Enter Iris, who gave the study, and the future of mindless driving machines, a genuine human voice. As noted by researcher Nicholas Epley, the voice allowed riders to infer the presence of a mind controlling the car, rather than code and sensors, and to relax physiologically. Herbie (and Alexa and Siri), looks like you’ve got competition.
