Yesterday, Leonardo DiCaprio was spotted clinging for dear life to a Citi Bike in New York. The event — meticulously captured by paparazzi — is not anomalous. In fact, Leo has made it a habit to cruise around the city on a cumbersome rented bike, wearing incognito frat-boy attire. But if you look closely, you’ll notice something about Leo’s environmentally friendly bike riding: He never — not once — wears a helmet when navigating the mean streets of New York by velocipede. Jesus, take the handlebars.
