Impossible to say. While you can say that had the offending vehicle had the same trajectory/position you'd have been hit more squarely, as I've pointed out several times had you been further out it would have had a very good chance of altering the driver's perception of what would be safe to attempt.

Again, impossible to say with any objective certainty, even at the level of saying it would improve your odds.
