Good ideas presented in the video. Not sure how applicable they are to 'real life scenarios'. But EVERY idea is 'another tool in the toolbox'. The more ya have, the more options available to the defender.
First thought - WHY is the defender allowing the attacker to tie them up and put them in a car (trunk or interior) in the first place? Is the plan to 'buy time' and 'make your move' later? That works great... in the movies. As noted in the clip, there's nothing 'good' for the defender from being taken to a secondary location. Being bound and taken as a hostage only benefits the attacker, except in rare instances.
Psychology - The attacker just held a gun to your head or knife to your throat, maybe smacked ya around a bit, and threw ya into the trunk or back seat. Do you REALLY want to take their 'promise' that they're going to 'just let you go' later? WHERE do you think they're taking you, to the shopping mall?
HOW do you think scumbag psychos like Ted Bundy and Gary Ridgeway were able to gain advantage over their victims to begin with? Neither of those (and others) are huge brutes. They need an advantage over the victim that doesn't require brute strength. Don't give it to them. One commonality in many such attacks and murders is that the victim willingly climbed into the vehicle with the attacker, for some unknown reason. Maybe there's a lesson to be learned in that.
The 'fight' begins when the attacker surprises the defender, holding a gun or knife on the potential victim. That's when the defenders 'defensive tactics' should begin. Don't relinquish control, 'hoping' to regain it 'later'. Take control.

I am always amazed at the propensity of folks to just do what they are told as they are walked down the road to a bad end. It is replayed throughout history, people kneeling in front of their own grave that they just dug with a gun to their head quietly waiting to die.
If they hand you a shovel kill them with it.
