I literally stopped reading after that. That is quite possibly one of the dumbest statements I've ever seen with regards to traffic safety. That's like somebody saying it's not a pedestrian's responsibility to make sure he doesn't walk out in front of a bus from between parked cars.
I would take your example a step further. A pedestrian crossing on a walk light or a bike going through his green light intersection better presume right of way to EVERY other vehicle on the road.
You hardly ever hear the dead guy bragging about how he was in the right. Almost never.
Assume that the 'other guy' is an idiot and you'll rarely be disappointed.
