Interesting work with interesting implications, including the advisability or consequences of using an antidote for stress reaction.
I do wonder why the victim didn’t scoot out the car on the other side, which is the response I would hope to have in a similar situation... Interesting to consider the role visualization and practice play.
If you have electronic doorlocks, you as the driver may just unlock the driver's side door while all the other doors remain locked. So if you are pushed over to the passenger's side of the car, you just can't scoot over and get out; the passenger's door is still locked, and only the driver can unlock it via a child-safety switch on the driver's door. At least, this is the way it has worked on my last few cars, GM and foreign.
A common response is to freeze...in spite of what the "fight or flight" crowd says. The book "What Every BODY is Saying" by Joe Nevarro an ex FBI counter intelligence guy talking about non-verbal communication postulates this very point. (An enjoyable read, by the way)
I think it is impossible to know how we might react in any given situation. I was just about to close my car door when I heard a voice and turned. Some guy had stuck his face in my door and I did what I supposed any normal person would do; I slammed the door on his face, threw the car in reverse and took off. I would be willing to bet the guy never did that again.
Most cars today have center consoles and bucket seats that would greatly slowdown that maneuver.
