The fixed-barrier standard was seen by the auto industry as a significant increase in test severity. At the same time, the NHTSA announced a long-term goal of setting a 30-mph fixed-barrier standard.[61][62] Due to the confusion related to the various proposed standards and an expectation that the NHTSA would not select the more stringent 30 mph fixed-barrier standard, Ford elected to voluntarily meet the 20 mph moving-barrier standard for all cars by 1973.[63][64] Ford and other automobile manufacturers objected to the more stringent fuel system safety standard and filed objections during the required comment periods of the proposed regulations.[65]
