This odd ad for Arlington’s “Car-Free Diet” initiative, currently appearing in D.C.-area Metro stations, encourages Metro riders to tone up—-and get flirting!—-on their commutes. Love-themed transportation initiatives may fly in Copenhagen, but since D.C. already has plenty of passengers looking for “love” with the closest unsuspecting target on a crowded Metro train—-sometimes non-consensually—-is this really a selling point of ditching the car? Say what you will about the economic and health benefits of public transportation, but at least car-drivers don’t have to deal with close-proximity leering. [Photo via Nikolas Coukouma].
