"Here lies the body of Jonathan Gray
Who died defending his right of way.
He was right, dead right, as he sped along
But he's just as dead now
As if he was wrong."
2 second rule, certainly and the pedestrian shouldn't have been on the crossing if the lights were against her, but personally, I wouldn't make someone jump back (or hit them). Under other circumstances, where there are no lights, pedestrians do always have the right of way as they're squishy.
