Fatality-free vehicles are not unprecedented. In fact, there already are some, and they’re not just Volvos. According to data from the Insurance Institute for Highway Safety, there are nine vehicle models — including the Volvo XC90 — in which no one in the United States died in the four years from 2009 to 2012, the most recent period for which data is available.

CNN lists the principal components of the system as:
