Crossing in the wrong spot or not, that's up to the police to decide. Guy layin in the middle of the road, bleeding.....now, that just demands help! You don't have to know first aid or be an EMT, at least get the poor guy out of the road, or wave oncoming traffic into another lane!!!!
Couple years back, a guy fell asleep at the wheel on his way to work, veered into the median and plowed into a pole holding a traffic sign of some sort (biiiiig pole). By the time fire and ambulance got there, other commuters had pulled over, pulled the guy out of his flaming truck, had made good progress in getting the bleeding stopped, and others were in the process of putting out the flames with various fire extinguishers they had on hand. One of the few benefits to living in Texas, I guess.
