If some lowlife is trying to force you to enter a car, why do suppose that might be? Answer: The lowlife wants to do something to you that he doesn’t think he can get away with at the current location.
If you get into that car, you are very likely to be murdered. Do whatever it takes to avoid getting into that car. A misdirection (like tossing a few dollar bills into the air) might distract the lowlife long enough to allow you to draw your handgun — or run like a scalded cat (low & zig-zag!).
A student in one of last year’s classes provided a real-life example. His twin brother (I’ll refer to him as Bill, not his real name), a manager at a grocery store, was taken hostage at gunpoint during an armed robbery by a man out on parole for another armed robbery. The robber was very agitated, and kept muttering things like, “they’ll never take me alive.” He took Bill outside, and demanded, “take me to your car!” As it turned out, Bill had the great good fortune to have completed a training seminar on how to act during an armed robbery and kidnapping that was provided by his company just a few weeks prior to this. He gave the answer that was suggested by his instructor: “I don’t have a car. I take the bus to work.” It was a lie, of course.
The lowlife was momentarily flustered, but since the lowlife had a car there (stolen, which was one reason he wanted another), he directed Bill to that one. When ordered to get in the driver’s side of the stolen car, Bill pretended to have trouble opening the door. The lowlife then reached for the door handle, and Bill had the opportunity to push the lowlife off-balance, and run for his life.
He ran crouched, and dodged between the other parked cars. The lowlife regained his balance and fired at Bill three times. All three shots missed — high. The lowlife then got into the car himself, put the gun to his own head, and committed suicide.
If Bill had gotten into that car, he almost certainly would not be around to tell that story to his grandchildren.
