Hmm he's either Captain Hindsight, or I don't know. It would have been a very close call. If i try and pretend she didn't get stopped, I count about 2 seconds to get across, which is about the same time it takes the car to hit the crossing after she falls. I think she would have made it, but not by much.
The fact that he's pointing at the car makes it seem like he was aware of it.
