Some critics argue that CAFE fines do not seem to be having much impact in the fuel economy drive. As noted in the 2007 United States Government Accountability Office Report to the Chairman of the U.S. Senate Committee on Commerce, Science, and Transportation (page 23) "Several experts stated that this is ("penalties") not enough of a monetary incentive for manufacturers to comply with CAFE." For example, in 25 years, from 1983 to 2008, Mercedes-Benz paid penalties 21 times and BMW paid penalties 20 times.
