Yeah, he was on the line. She wasn't. She should have yielded, being that she was forced off line. But he shouldn't have presumed she was going to yield. That's what happens when you lose the mental game.
Closest analysis yet of what happened. A couple of comments....
First, this was terrible marshaling....haven't seen things this bad since Italy 1995 or so. Incredible.
Second, as to the accident, street circuits are awfully narrow, with low grip, so there is no option of "giving room" on the outside as you would do at, say, any of the Tilke courses. The inside guy has to know he/she is going to be chopped if they are not right alongside under braking. So the "old guy" took his line and was OK in doing so. However, he should know who he's chopping - it just didn't work out. But there should be no penalty for the old guy....the car trying to overtake didn't get it done and therefore should have backed off.
Third, who on earth chooses a Bentley to be the pace/safety car on a Lotus field?????? I'm wondering if this was an SNL skit, but they were actually serious! The epitome of lightness, the Elise, is being led about by a 2.5 ton behemoth that can barely get out of its own way......I suppose this is an instance of marketing outweighing logic? As Einstein said, "the only thing more common in the universe than hydrogen is stupidity."
