Honestly, I'll grant you the carbide glass breaker, although there are videos showing that many are just soft steel and won't actually break a window. But there's a lot of seat belt material near the pillar that isn't laying against the body of the victim. If you just had a regular halfway sharp pocket knife, you would want to cut the belt there, or near the buckle to reduce the chances of cutting the victim with your knife.
So, to me, those extra doo-dads on a knife make the knife uncomfortable to carry/use and for nearly no gain.
This, of course, simply the opinion of a random person online whose consideration of similar styled knifes led him to a different conclusion.
Some of the new cars are using laminated glass in the side windows now:
Does Your Car Have Laminated Glass?
A third of 2018 model-year vehicles have laminated glass in their side windows, AAA says. To find out whether your car has tempered or laminated side windows, read the label in the bottom corner the window, or check directly with the manufacturer. Make sure to check every window, as it’s common for at least one side window to be made from breakable tempered glass.https://www.cars.com/articles/tough...could-make-it-hard-to-escape-your-car-405870/
