In the United States, government policies aimed at encouraging smaller, more fuel-efficient vehicles to reduce oil consumption and carbon emissions had unintended consequences during the 1973 oil crisis. These policies, known as CAFE (Corporate Average Fuel Economy) regulations, were designed to promote fuel efficiency. However, automakers responded by producing larger vehicles like SUVs and pickup trucks, which faced less stringent fuel efficiency checks. Consequently, consumers began to prefer larger cars, resulting in the opposite of the intended conservation efforts.
