3.3 The influence of mandatory ethical settings on willingness to purchase As a baseline question, we asked participants how likely it is that they would purchase a driverless car in ten years’ time (if their current car needed replacing) without specifying any safety programming. In the UK, the median response on the 1 (not at all likely) to extremely likely (7) scale was 5, with a Mean of 5.13 (SE = .119). In Japan, the median response was 6, with a Mean of 5.66 (SE = .068).
