A rising classical-music star is running late for a performance. He is carrying his guitar with him. Hailing a cab, he arrives at the Symphonic Hall. Quickly paying the driver, he grabs the strap of the guitar case and starts to exit the cab. The strap catches on the door, which slams shut. The cab immediately moves on to the next fare. The guitarist is yanked off his feet and dragged half a block, still holding the strap of the guitar case. The strap breaks, the cab keeps going, and the guitarist is hit by another car. With two badly broken arms, one broken leg, a few broken ribs and a concussion, he is taken to the hospital. Discuss your answer, assuming jurisdiction is in Illinois.

Is the musician responsible for his injuries at all? why or why not?
