You can say whatever you want! Your entitled to your opinion and I am entitled to mine! Stop or don't stop, I don't really care what you do or don't do!
Just my opinion if someone gets in an accident in front of me I am going to stop and render care as it is the way I was brought up to help my fellow citizen. You can do whatever you want!
Just my two cents! If I was in a car accident I would be happy to have a concerned citizen stop and provide comfort if nothing else. Maybe it is just me but if an accident happened in front of me I would call 911 and pull over in a safe area and render whatever care within my scope of practice...
