Urban planner Colin Hughes was cycling down the center bike lanes on Pennsylvania Avenue on Wednesday morning when he was suddenly met with two tons of metal crossing in front of his path.

As he tells it, he slammed right into the cab that cut in front of him to make an illegal U-turn across the bike lanes in order to pick up a customer in front of D.C.’s city hall. Hughes, who bikes to work every day, said he was knocked off his bike by the collision.
