Josef Newgarden accepts penalty, responsibility for push to pass violation: "I don't think it's very believable, even when I tell the story back."

Reigning Indianapolis 500 champion Josef Newgarden is accepted blame for manipulating the push-to-pass system in his season-opening win, calling it an embarrassment.

Josef Newgarden insisted he is "not a liar" and said he didn't know he had broken IndyCar rules until Monday, the day after the manipulated push-to-pass systems were discovered, leading to his disqualification from the season opener.
