In the mid 1960's, my parents bought my sister a Mustang convertible. We had to wear our seatbelts in the car religiously. As a result, I'm uncomfortable being in a car without a seat belt stretched across my body. Besides, I race cars wear seat belts are required. My mother never took to liking seat belts even after it became Ohio law requiring one to wear one. She'd wear one grudgingly until she past away
I'm old enough to have lived in both Indiana and Ohio before there were seatbelt laws, and, drove big trucks over-the-road for for a few years before there were mandatory laws. In fact, my first few trucks only had lap belts... so no one could tell whether or not I was wearing one, anyway, including the DOT. That, of course, changed... and for the better, although I think one's decision to wear a seatbelt should be a personal choice, not a law, per se. Back when I was young and indestructable... and rode motorcycles... I hardly ever wore a helmet. These days, I won't ride around the block after an oil change without a helmet. I like that wearing a helmet is, at least in Texas, somewhat of a personal freedom.
As far as the Hollywood OP comments... and I think CapnMac eluded to this... actors just act. FWIW, from what I've seen, true knowledge of firearms is somewhat limited in Hollywood... a firearms-ignorant director and crew wouldn't know to tell an actor or actress to keep their booger hook off the trigger, or anything else... it's all about optics. That's why, as a firearm enthusiast, it's always so refreshing to see a movie with realistic firearms use, among other things, but those are exceptions and not the rule.
Think about it... how many times have you seen completely made-up firearms nonsense in a movie or TV show? Kop Killer Bullets, Glocks have a ceramic frame to avoid detection, full-auto firearms on sale behind the LGS counter, exploding tip bullets... the list goes on.
