AP Exclusive: Tony Stewart unsure if he'll ever race sprint cars again

HUNTERSVILLE, N.C. - Tony Stewart found no greater joy than escaping his everyday life and climbing behind the wheel of a sprint car.

But in the wake of the death of Kevin Ward Jr., Stewart is unsure if he will ever race a sprint car again. Ward was killed when Stewart's car struck him as Ward walked on an upstate New York dirt track.

Stewart spoke to The Associated Press in his first interview since a grand jury decided against charging the NASCAR star in Ward's death. He could face a civil lawsuit.

"I would say it's going to be a long time before you ever see me in a sprint car again, if ever," Stewart said. "I don't have any desire at this moment to get back in a car."
