Transportation Secretary Sean Duffy’s thoughts took a strange path when he complained about “DEI bike lanes” in a baffling X post last Tuesday.In what seemed like a desperate attempt to drag infrastructure fixes into a one-sided culture war, Duffy asked, “Remember when Biden and Boot-edge-edge used YOUR MONEY for DEI bike lanes and climate change? THAT’S OVER.”(“Boot-edge-edge” is a reference to Pete Buttigieg, who steered the Department of Transportation during President Joe Biden’s administration.)Under his leadership, Duffy said, his department will redirect $1.73 billion in grants from “Biden-era DEI pet projects” to roads — presumably those without bike lanes — bridges and shipping ports he described as “America’s actual backbone.”Remember when Biden and Boot-edge-edge used YOUR MONEY for DEI bike lanes and climate change?THAT’S OVERI just redirected $1.73 billion in USDOT grants away from Biden-era DEI pet projectsNow this funding is officially locked in to fix America’s actual backbone: ROADS,… pic.twitter.com/J9PuCgTqAv— Secretary Sean Duffy (@SecDuffy) July 7, 2026The former lawmaker seemed to be griping about the Transportation Department awarding around $1 billion in grants in 2021 to state and local projects it said were designed to “improve infrastructure, strengthen supply chains, make us safer, advance equity, and combat climate change.”Duffy has derisively called initiatives to combat the climate crisis “woke,” but the benefits of bike lanes go far beyond just helping the environment.In addition to reducing people’s reliance on cars and curbing carbon emissions, research shows that offering more ways for people to get from point A to point B significantly reduces traffic, improves public health and even boosts businesses along bike routes.While Duffy’s bike lane beef made him look ridiculous, the secretary doesn’t seem like the type to get embarrassed easily.During a Monday event at the White House, President Donald Trump mocked the former lumberjack and reality TV personality for holding a record for speed climbing “stupid trees.”Unfazed, Duffy lavished the president with praise mere minutes after, telling him, “You don’t do anything that’s small. Everything you do is big. It’s huge. It’s the best. It’s the greatest. America loves you.”
