Are you sure about that? It would mean that it's technically illegal to cross a road unless you're absolutely certain that there can't be a speeding driver around the next corner who's gonna get to you faster than you can react. Or that you aren't allowed to cross the street at a green light even when all the cars are waiting because you can't actually be certain that a car isn't gonna start driving suddenly and run you over. Or that someone tailgating you is somehow caused in part by you.
It's pretty ridiculous to claim that both sides failed to comply with the laws in every incident.
