Good post. I think many people are trained to drop to the ground...that comes after attempting to run. If you are caught, then you drop to the ground. If the perp has you and is trying to drag you into a vehicle, dropping to the ground makes this task much harder. It is about gravity, weight distribution and kinesics (or the bodys ability to function to lift, carry, etc using poor body mechanics). So, yes, if someone grabs you, it is so much harder to lift or drag say 100 lbs off the ground, then to grab that person at the perps waist level and heave. As a parent, if you have ever have had a child do what I call melting or floppy kid when they don't get their way, most of us can understand how hard it is to pick up that child off the floor...LOL. Even a toddler can be hard to pick-up. So dropping to the ground, can save lives if the perp already has you.
If a predator demands you get into a vehicle, studies have shown that it is best to avoid that at all costs, even at risk of your life. The reason being is most predators have a "plan" in their minds that they have fantasized about, enjoy and finally get the energy to act on. It starts with day dreaming, then they get so attached to that scenario, they must act on it to ease or satisfy the turmoil in side. That is why people have MO's or commit similar crimes...it is that obsession and psychological attachment to a certain scenario in their heads. Part of what they are doing by moving a victim from point A is acting on this plan and fantasy they created in their heads so they can be at point B where they can get off on their fantasy. Once you are in a vehicle, your future is pretty much predetermined. Some people think they can talk their way out of things or comply to live, but if the perp thinks death is part of his plan, it is part of the plan. By not getting in the vehicle you disrupt the pre-planned scenario. Often when perps fantasize, they don't plan for the victim to fight back. So, by refusing to get in a vehicle you actually save your own life, by disrupting the perps plans and throwing of the power balance.
I think with both of the run like hell scenarios, if you have the chance, do run like hell. However, most training recognizes that usually by the time the person realizes they are in danger; they actually are restrained or physically controlled by the perp. I think the run like hell thing IS omitted, because in most situations where you need life-saving training, having too many steps...like run, if that does not work do this, if that does not work try this, etc...Can cause more confusion with the victim and actually make them more likely to forget every type of training, self doubt themselves, the victims mind often underestimates the level of threat or goes into a denial state and easily play into the perps hands. The purpose of training is to give very simple steps the average person can utilize in a horrific situation where they do not have time or mental clarity to process things. Kind of like Fire safety
.Stop, Drop, Roll. Simple, people can remember that in crisis most of the time.
