We know the car was going roughly 40mph, so that puts some constraints on the minimum response time that was available. Unless this woman literally catapulted in front of the car, there were at least 4’ of lateral walking pace worth of 40mph time to react. You do need to make assumptions about how fast she was moving, of course, and as has been noted elsewhere in the thread you have to assume that the driver was in the left lane for this scenario to even be remotely plausible. Even in this sequence, the car should have been able to substantially decelerate but, looking at the pictures, that doesn’t seem to have happened.
