There is always that one story, that is an outlier. I've heard many. But it's not the majority of cases.
I was a FF/EMT for 10 years, and my Dad did it for 20. In ALL those years, neither of us has cut a dead person out of a seatbelt. They were alive every time we got there; had a chance.
But I have put brain matter in a plastic bag, and washed of the remains with a fire hose.

I worked with a very eccentric guy named Frank years ago, big guy, loud, funny as hell.
He always swore he'd never wear a seatbelt because he wanted to "jump out" before an accident happens. He said he drove his Eldorado with his hand on the door handle, and felt he could also kick the door off the hinges, and ride it out of there like a sled. He made work interesting! This was Government Contracting work for the Intelligence Community. We are still not sure how he kept his clearance.

My brother had to call USCG this last summer for a boat without passengers circling in the North Channel of the St Clair river. I thought all these people that come up with this stuff believed in evolution, where does thinning of the herd come in? It's time to take the warning tags off of hair dryers. If your dumb enough to use it in the shower, you'll learn. It's like the law they tried to pass to put holes in buckets so kids wouldn't drown. My granddaughter is only 2 and she knew as soon as she was old enough to walk, not to put her head in to a bucket of water. You can't legislate common sense. I've done some really crazy things on the water and I know enough if I'm feeling crazy to put on my impact rated jacket and buckle it up and connect the lanyard. Hitting the water at over 70 tends to rip apart regular jackets, don't ask how I know that.

Covered vessel = boat less then 26 feet

I have said as a sort of joke for years that we should get rid of seat belt laws, anti lock brakes, air bags, skid controls etc. Learn that if you mess up you can get hurt.

Or make everyone ride a motorcycle for 2 years, you learn to drive defensively or die.

Again this is a joke but sometimes I do think to many drive with no fear of getting hurt.

I make my living looking at and reviewing wrecks all day long, I understand both sides of the coin, yes there are always the stories of someone who walked away. The point I make is, it is your responsibility to be in control of your vehicle (car, boat, plane, etc.) and take responsibility for your passengers. Today many drivers rely on ADAS systems to a fault. People think you can drive un-responsible because if something happens, kill switches, airbags, seatbelts and avoidance systems are the answer. Yes they all can help during the unexpected, however common sense and responsibility should come first. Passing a law does not insure either.

1000`s of new laws get passed every year, nanny state laws like turn on your headlights if your wipers are on.
How about you build me some roads and schools and whatever other essential service that are needed, protect the border and stay the hell out of my life . I want less government involved in my life , not more.

in Louisiana its a low to have a kill stitch hooked to you on a tiller handle powered boat. its easy to see and people get tickets all the time.

I have worked for the Feds for almost 30 years. Trust me when I say nothing is done so poorly that the Federal government can't do worse. I see it on a daily basis.

Insurance Lobby is the third-largest lobbying group (by money spent) in the US. THAT's who you thank for this piece of legislation.

My first thought would be this is pushed by insurance companies. In the event of an accident that results in significant pay out$$$$$, this gets insurance company off the hook. No kill switch=no pay.
