The first thing your told before you get on any track is DO NOT GET OUT OF YOUR CAR. Ward needed to express himself to the celebrity, a bit of posturing that got him killed. Even if Stewart shares some fault, the huge majority of it rests with Ward.

They should have red flagged the race after he got out of his car, but this is different world than the one I'm used to.

I will say, at first I thought Stewart's line of sight might have been blocked, but it appears that he should have had a clear view of Ward. However, on track, your eyes are only looking for cars, corners and walls NOT people, easy to miss if your not expecting a guy in a black suit hopping around a live track.
