A historic two-year national advocacy campaign defending Americans’ right to choose internal combustion, hybrid, or electric vehicles. In response to California’s 2035 zero-emission mandate (adopted by 11 states), SEMA launched a multi-channel political, media, and grassroots campaign to protect “vehicle choice.” Through the “Driving Force Action” SuperPAC, digital activism, and direct congressional lobbying, SEMA mobilised 7,000 small businesses, 70 million automotive enthusiasts, and lawmakers across party lines. The effort resulted in bipartisan Congressional votes repealing California’s Advanced Clean Cars II waiver, reaffirming technology neutrality and preserving automotive freedom nationwide.
