Thomas Massie did warn that federal law requires automakers to install impaired-driving detection technology (colloquially called 'kill switches') in all new cars starting with 2026 models. His attempt to block federal funding for the mandate failed in January 2026 when 268 House members — including 57 Republicans and 211 Democrats — voted to preserve it. The post misleadingly frames this as a 'bipartisan effort to defund' when the bipartisan outcome actually kept the mandate in place.
