Working out the implications of technological change is hard. It’s hard because guessing which technologies will mature when is not straightforward more than a short time ahead; it’s even harder because the real impact comes from second and third order effects which may not be immediately (or at all) obvious just from understanding the technology itself. This post explores the implications of autonomous vehicles for the design of the vehicles themselves and the roads they run on, as well as for land use, employment, in-car entertainment and murder investigations – interesting not just as a case study, but as a way of thinking about these kinds of uncertainties.
