My dad told me a story about how one day he passed by a car with it's hood up and a women trying to flag him down. He turned around and was slowing down to help when he looked over and saw a guy that was trying to hide in the bushes by the car he decided to haul butt outta there. He found a patrol car and told them what was up and where the women and the man was. What I took away from this little story is it's better to just report the stranded person cause you never know who you may be trying to help. Oh and something I learned many times since then is good deeds rarely go unpunished so be very careful out there.
